How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)

Apparently, there was a /Users/myusername/local folder that contained a include with node and lib with node and node_modules. How and why this was created instead of in my /usr/local folder, I do not know.

Deleting these local references fixed the phantom v0.6.1-pre. If anyone has an explanation, I'll choose that as the correct answer.

EDIT:

You may need to do the additional instructions as well:

sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/{npm*,node*,man1/node*}

which is the equivalent of (same as above)...

sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node* /usr/local/lib/dtrace/node.d ~/.npm ~/.node-gyp 

or (same as above) broken down...

To completely uninstall node + npm is to do the following:

go to /usr/local/lib and delete any node and node_modules go to /usr/local/include and delete any node and node_modules directory if you installed with brew install node, then run brew uninstall node in your terminal check your Home directory for any local or lib or include folders, and delete any node or node_modules from there go to /usr/local/bin and delete any node executable

You may also need to do:

sudo rm -rf /opt/local/bin/node /opt/local/include/node /opt/local/lib/node_modules
sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node.1 /usr/local/lib/dtrace/node.d

Additionally, NVM modifies the PATH variable in $HOME/.bashrc, which must be reverted manually.

Then download nvm and follow the instructions to install node. The latest versions of node come with npm, I believe, but you can also reinstall that as well.

---

For brew users, OSX:

To remove:

brew uninstall node; 
# or `brew uninstall --force node` which removes all versions
brew cleanup;
rm -f /usr/local/bin/npm /usr/local/lib/dtrace/node.d;
rm -rf ~/.npm;

To install:

brew install node;
which node # => /usr/local/bin/node
export NODE_PATH='/usr/local/lib/node_modules' # <--- add this ~/.bashrc

You can run brew info node for more details regarding your node installs.

consider using NVM instead of brew

NVM (node version manager) is a portable solution for managing multiple versions of node

https://github.com/nvm-sh/nvm

> nvm uninstall v4.1.0
> nvm install v8.1.2
> nvm use v8.1.2
> nvm list
         v4.2.0
         v5.8.0
        v6.11.0
->       v8.1.2
         system

you can use this with AVN to automatically switch versions as you hop between different projects with different node dependencies.

I know this post is a little dated but just wanted to share the commands that worked for me in Terminal when removing Node.js.

lsbom -f -l -s -pf /var/db/receipts/org.nodejs.pkg.bom | while read f; do  sudo rm /usr/local/${f}; done
 
sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*

UPDATE: 23 SEP 2016

If you're afraid of running these commands...

Thanks to jguix for this quick tutorial.

First, create an intermediate file:

lsbom -f -l -s -pf /var/db/receipts/org.nodejs.node.pkg.bom >> ~/filelist.txt

Manually review your file (located in your Home folder)

 ~/filelist.txt

Then delete the files:

cat ~/filelist.txt | while read f; do sudo rm /usr/local/${f}; done

sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*

For 10.10.5 and above

Thanks Lenar Hoyt

On Mavericks I install it from the node pkg (from nodejs site) and I uninstall it so I can re-install using brew. I only run 4 commands in the terminal:

sudo rm -rf /usr/local/lib/node_modules/npm/ brew uninstall node brew doctor brew cleanup --prune-prefix

If there is still a node installation, repeat step 2. After all is ok, I install using brew install node

https://stackabuse.com/how-to-uninstall-node-js-from-mac-osx/

Run following commands to remove node completely from system in MACOS

sudo rm -rf ~/.npm ~/.nvm ~/node_modules ~/.node-gyp ~/.npmrc ~/.node_repl_history
sudo rm -rf /usr/local/bin/npm /usr/local/bin/node-debug /usr/local/bin/node /usr/local/bin/node-gyp
sudo rm -rf /usr/local/share/man/man1/node* /usr/local/share/man/man1/npm*
sudo rm -rf /usr/local/include/node /usr/local/include/node_modules
sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /usr/local/lib/dtrace/node.d
sudo rm -rf /opt/local/include/node /opt/local/bin/node /opt/local/lib/node
sudo rm -rf /usr/local/share/doc/node
sudo rm -rf /usr/local/share/systemtap/tapset/node.stp

brew uninstall node
brew doctor
brew cleanup --prune-prefix

After this I will suggest to use following command to install node using nvm (check https://github.com/nvm-sh/nvm for latest version)

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash

from https://github.com/nvm-sh/nvm

Why nvm? this is a good question, there will be projects requiring different versions of node, i.e. A requires node version 12 while B requires node version 14. This version management of node is provided by nvm only.

I have summarized the existing answers and made sure Node.js is COMPLETELY ERASED along with NPM.

Lines to copy to terminal:

brew uninstall node;
which node;
sudo rm -rf /usr/local/bin/node;
sudo rm -rf /usr/local/lib/node_modules/npm/;
brew doctor;
brew cleanup --prune-prefix;

downgrade node to 0.10.36

  sudo npm cache clean -f
  sudo npm install -g n
  sudo n 0.10.36

upgrade node to stable v

  sudo npm cache clean -f
  sudo npm install -g n
  sudo n stable

I'm not sure if it's because I had an old version (4.4.5), or if it's because I used the official installer, but most of the files referenced in other answers didn't exist on my system. I only had to remove the following:

~/.node-gyp
~/.node_repl_history
/usr/local/bin/node
/usr/local/bin/npm
/usr/local/include/node
/usr/local/lib/dtrace/node.d
/usr/local/lib/node_modules
/usr/local/share/doc/node
/usr/local/share/man/man1/node.1
/usr/local/share/systemtap/tapset/node.stp

I decided to keep ~/.npm because I was planning on reinstalling Node with Homebrew.

Complete uninstall Nodejs on macOS Big Sur version 11.2.3 (20D91)

Introduction

First things first, I want to say thank you for sharing this trick @tonymtz.

My system is running macOS Big Sur version 11.2.3 (20D91) with nodejs Latest Current Version: 15.14.0 (includes npm 7.7.6) installed from the official website.

I tried to fully uninstall nodejs on my MacBook Pro in order to re-install it with homebrew package manager using:

lsbom -f -l -s -pf /var/db/receipts/org.nodejs.pkg.bom | while read f; do  sudo rm /usr/local/${f}; done

but I was facing an issue like @AhteshamShah mentioned in @JohelAlvarez's answer:

When fired first command getting: can't open /var/db/receipts/org.nodejs.pkg.bom: No such file or directory **** Can't open /var/db/receipts/org.nodejs.pkg.bom. – Ahtesham Shah Jun 20 '19 at 5:09

I dived into the original post linked by @JohelAlvarez, reading all the comments and I've found this comment from @e2tha-e:

@tonymtz On my installation of Node v4.0.0 on Yosemite 10.10.5, the first line needed to be lsbom -f -l -s -pf /var/db/receipts/org.nodejs.node.pkg.bom | while read f; do sudo rm /usr/local/${f}; done A different filename from org.nodejs.pkg.bom Otherwise, this worked like a charm!

@e2tha-e was right, on macOS Big Sur version 11.2.3 (20D91) with nodejs Latest Current Version: 15.14.0 (includes npm 7.7.6) installed from official website, the file name is not org.nodejs.pkg.bom but org.nodejs.node.pkg.bom .

You can check this when you cd /var/db/receipts/ && ls -la.

Solution for installation from Nodejs's official website

With your preferred Terminal, fully uninstall Nodejs from your system like this :

Option 1

lsbom -f -l -s -pf /var/db/receipts/org.nodejs.node.pkg.bom | while read f; do sudo rm /usr/local/${f}; done sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*

Option 2

Go to /var/db/receipts/ and delete any org.nodejs.*

cd /var/db/receipts/ && ls -la sudo rm -rf org.nodejs.*

Go to /usr/local/lib and delete any node and node_modules

cd /usr/local/lib && ls -la sudo rm -rf node*

Go to /usr/local/include and delete any node and node_modules directory

cd /usr/local/include && ls -la sudo rm -rf node*

Check your $HOME directory for any "local" or "lib" or "include" folders, and delete any "node" or "node_modules" from there.

Go to /usr/local/bin and delete any node executable

cd /usr/local/bin && ls -la sudo rm -rf /usr/local/bin/npm sudo rm -rf /usr/local/bin/node

You may need to do this too:

sudo rm -rf /usr/local/share/man/man1/node.1 sudo rm -rf /usr/local/lib/dtrace/node.d sudo rm -rf ~/.npm

After that, you can check if there is still node in your system with which node or find all occurrences for node in your system.

Tips

Search where node files are with find / -name 'node' | sed -E 's|/[^/]+$||' |sort -u Before running shared code by others, check your directories before to make sure you write the right file name.

---

Delete node and/or node_modules from /usr/local/lib ex code: cd /usr/local/lib sudo rm -rf node sudo rm -rf node_modules

Delete node and/or node_modules from /usr/local/include

Delete node, node-debug, and node-gyp from /usr/local/bin

Delete .npmrc from your home directory (these are your npm settings, don't delete this if you plan on re-installing Node right away)

Delete .npm from your home directory

Delete .node-gyp from your home directory

Delete .node_repl_history from your home directory

Delete node* from /usr/local/share/man/man1/

Delete npm* from /usr/local/share/man/man1/

Delete node.d from /usr/local/lib/dtrace/

Delete node from /usr/local/opt/local/bin/

Delete node from /usr/local/opt/local/include/

Delete node_modules from /usr/local/opt/local/lib/

Delete node from /usr/local/share/doc/

Delete node.stp from /usr/local/share/systemtap/tapset/

---

After

brew uninstall node

I had to know which node

which node

then remove that

rm -rf /usr/local/bin/node

---

Complete uninstall Node.js on macOS Monterey version 12.0.1

To check the current node version installed on your system:

# node -v
# v14.15.0

Enter the given below commands to delete Node from your system:

# cd /usr/local/include
# sudo rm -R node
# cd ../lib
# sudo rm -R node_modules
# cd ../bin
# sudo rm -R node

to check that node doesn't exist anymore

# node -v
# -bash: node: command not found

Install Node.js on macOS Monterey version 12.0.1

Download the LTS version of node from the official website

Double click on the node-v16.13.1.pkg installation package and continue with the default settings Type node -v in your terminal to print the current installed version of node : v16.13.1 & npm -v to print the current npm version installed on your machine : 8.1.2

---

Worked for me.

$node --version

v11.1.0

$nvm deactivate

$nvm uninstall v11.1.0

---

Steps to Uninstall NodeJS:

For MacOS Monterey with M1 chip, please follow the link below to uninstall node completely from the system. I have tried multiple ways but this one worked finally.

Uninstall NodeJS & NPM from Mac M1 Monterey

Additionally, please execute the following commands at the end to remove node related directories from bin folder.

sudo rm -R node-sass
sudo rm -R npm
sudo rm -R npx

To verify that node is removed:

node --version

It should say command not found.

Steps to Install NodeJS:

Enable Rosseta terminal on your Mac with M1 chip. How to enable Rosseta terminal

Use nvm (Node Version Manager) to install NodeJS on your machine. Why nvm?? Because you can run multiple versions of NodeJS (you can work with a new app as well as a Legacy app).

How to install multiple versions of NodeJS using nvm

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

Create a .zshrc file if not exists.

touch ~/.zshrc

Install node using nvm.

nvm install node # "node" is an alias for the latest version
nvm install 14.7.0 # or 16.3.0, 12.22.1, etc

To verify the number of NodeJS versions available:

nvm ls

---

If you have already installed nvm then execute the following commands

nvm deactivate - This will remove /.nvm/*/bin from $PATH

nvm list - To list out all the versions of node installed in the system

nvm uninstall in you can specify all the versions you want to uninstall.

It is always a good that you install node using nvm and uninstall using nvm rather than brew .

This solution worked for me.

Additional Commands

which node to know the path of node installed in your system. You can rm this directory to uninstall node manually. Then you may need to adjust the PATH file accordingly.

---

Expanding on Dominic Tancredi's awesome answer, I've rolled this into a bash package and stand-alone script. If you are already using the "Back Package Manager" called bpkg you can install the script by running:

bpkg install -g brock/node-reinstall

Or you can have a look at the script on Github at brock/node-reinstall. The script allows you to re-install node using nvm or nave, and to specify a node version as your default.

---

Additional to the main answer I needed to remove all npm instances found in:

rm -rf /usr/local/share/man/man1/npm*

---

maybe you need to make

hash -r 

it helps with problem of symlink

$ node -v
$ bash: /opt/local/bin/node: No such file or directory

---

The best way is to download an installer package: .pkg on mac. Prefer the latest stable version.

Here is the link: Node.js

This package will eventually overwrite the previous version and set environment variables accordingly. Just run the installer and its done within a few clicks.

---

I have been hit by an issue during uninstall of Node.js on my mac. I had some strange behavior like npm is still there even after having to remove it with all this.

It was because I had an old install done with macport. So you also have to uninstall it using port:

sudo port uninstall nodejs

It may have installed many different versions of Node.js so uninstall them all (one by one).

---

You can clone https://github.com/brock/node-reinstall and run the simple command as given in the repository.After that just restart your system.
This is the simplest method and also worked for me.

---

I had installed Node.js from source downloaded from the git repository. I installed with:

./configure
$ make
$ sudo make install

Because the make file supports it, I can do:

$ sudo make uninstall

---

As a companion to the answers explaining cleanup and install via homebrew, I found that homebrew itself provided clear indications of the symlink clashes.

Unfortunately it provides these one by one as it encounters them, so it is a little laborious, but it does seem to find all the clashes and was the only way I could get a clean install with homebrew.

Essentially, the process is:

use homebrew to uninstall node clean homebrew use homebrew to install node and note any flagged clashing file delete the flag clashing file (or whole directory if it is a 'node' directory) goto step 1 until you get a clean install

https://i.stack.imgur.com/498rO.jpg

Here is a screen output from the last steps of my install - you can see it results in a clean install (eventually...):

First of all, you need to deactivate node: (mac) after install new node version.

nvm deactivate

This is removed /Users/user_name/.nvm/*/bin from $PATH

And after that node was updated

node --version
v10.9.0

---

Docker - alternative approach

Docker is some-kind of super-fast virtual machine which can be use to run tools like node (instead install them directly on mac-os). Advantages to do it are following

all stuff ('milions' node files) are install inside docker image/container (they encapsulated in few inner-docker files)

you can map your mac directory with project to your docker container and have access to node - but outside docker, mac-os sytem don't even know that node is installed. So you get some kind of 'virtual' console with available node commands which can works on real files

you can easily kill node by find it by docker ps and kill by docker rm -f name_or_num

you can easily uninstall docker image/containers by one command docker rmi ... and get free space - and install it again by run script (below)

your node is encapsulated inside docker and don't have access to whole system - only to folders you map to it

you can run node services and easily map they port to mac port and have access to it from web browser

you can run many node versions at the same time

in similar way you can install other tools like (in many versions in same time): php, databases, redis etc. - inside docker without any interaction with mac-os (which not notice such software at all). E.g. you can run at the same time 3 mysql db with different versions and 3 php application with different php version ... - so you can have many tools but clean system

TEAM WORK: such enviroment can be easily cloned into other machines (and even to windows/linux systems - with some modifications) and provide identical docker-level environment - so you can easily set up and reuse you scripts/dockerfiles, and setup environment for new team member in very fast way (he just need to install docker and create similar folder-structure and get copy of scripts - thats all). I work this way for 2 year and with my team - and we are very happy

Instruction

Install docker using e.g. this instructions

Prepare 'special' directory for work e.g. my directory is /Users/kamil/work (I will use this directory further - but it can be arbitrary) - this directory will be 'interface' between docker containers and your mac file ststem. Inside this dir create following dir structure: /Users/kamil/work/code - here you put your projects with code /Users/kamil/work/tools /Users/kamil/work/tools/docker-data - here we map containers output data like logs (or database files if someone ouse db etc.) /Users/kamil/work/tools/docker /Users/kamil/work/tools/docker/node-cmd - here we put docker node scripts

inside tools create file .env which will contain in one place global-paths used in other scripts toolspath="/Users/kamil/work/tools" codepath="/Users/kamil/work/code" workpath=/Users/kamil/work

innside dir ../node-cmd create file dockerfile with following content # default /var/www/html (mapped to .../code folder with projects) FROM node WORKDIR /work # Additional arbitrary tools (ng, gulp, bower) RUN npm install -g n @angular/cli bower gulp grunt CMD while true; do sleep 10000; done # below ports are arbitrary EXPOSE 3002 3003 3004 4200

innside dir ../node-cmd create file run-container with following content (this file should be executable e.g. by chmod +x run-container) - (notice how we map port-s and directories form external 'world' to internal docker filesystem) set -e cd -- "$(dirname "$0")" # this script dir (not set on doubleclick) source ../../.env toolsdir=$toolspath/docker-data workdir=$workpath if [ ! "$(docker ps | grep node-cmd)" ] then docker build -t node-cmd . docker rm -f node-cmd |: docker run -d --name node-cmd -p 4200:4200 -p 4201:4201 -p 3002:3002 -p 3003:3003 -p 3004:3004 -v $toolsdir/node-cmd/logs:/root/.npm/_logs -v $workdir:/work node-cmd fi

ok now you can add some project e.g. work/code/myProject and add to it following file 'run-cmd' (must be executable) cd -- "$(dirname "$0")" ../../tools/docker/node-cmd/run-container docker exec -it node-cmd bash -c "cd /work/code/myProject; bash"

then if you run above script (by double-click), you will see console with available node commands in project directory e.g. npm install

to run project in background (e.g some serwice) e.g. run web-server angular-cli application you can use following script (named run-front -must be executable) - (you must also edit /etc/hosts file to add proper domain) cd -- "$(dirname "$0")" open "http://my-angular.local:3002" ../../tools/docker/node-cmd/run-container docker exec -it node-cmd /bin/sh -c "cd /work/code/my-angular-project; npm start" cat # for block script and wait for user ctrl+C

---

In my case none of the other answers worked because I previously downgraded to node8. So instead of doing above, following worked for me:

which node

which returned /usr/local/bin/node@8 instead of /usr/local/bin/node

so i executed this command:

brew uninstall node@8

which worked and then downloaded latest pkg from official site and installed. After that I had to close my terminal and start again to access new version

---

If you're unable to locate node just run whereis node and whereis npm and whereis nvm and you can remove the listed directories as needed.

You'll also need to entirely close your terminal and reopen it for changes to take effect.

This fixed it for me Fixing npm On Mac OS X for Homebrew Users. And it does not require too many steps.

Just go to the solution part if you don't care about the why.

Here is the relevant part for convenience:

Solution

This solution fixes the error caused by trying to run npm update npm -g. Once you're finished, you also won't need to use sudo to install npm modules globally.

Before you start, make a note of any globally installed npm packages. These instructions will have you remove all of those packages. After you're finished you'll need to re-install them.

Run the following commands to remove all existing global npm modules, uninstall node & npm, re-install node with the correct defaults, configure the location for global npm modules to be installed, and then install npm as its own package.

rm -rf /usr/local/lib/node_modules
brew uninstall node
brew install node --without-npm
echo prefix=~/.npm-packages >> ~/.npmrc
curl -L https://www.npmjs.com/install.sh | sh

Node and npm should be correctly installed at this point. The final step is to add ~/.npm-packages/bin to your PATH so npm and global npm packages are usable. To do this, add the following line to your ~/.bash_profile:

export PATH="$HOME/.npm-packages/bin:$PATH"

Now you can re-install any global npm packages you need without any problems.

@lfender6445 answer worked just fine for me to uninstall

Now to reinstall, I had problems installing the last version instead of the most stable one, so to install a specific node version you should do:

brew install node@10 // 10 is the version I want
brew link node@10
