'heroku' does not appear to be a git repository

To add a Heroku app as a Git remote, you need to execute heroku git:remote -a yourapp.

Source: Deploying with Git

---

You could try the following in your root directory:

// initialize git for your project, add the changes and perform a commit

git init
git add .
git commit -m "first commit"

// create heroku app and push to heroku

heroku create
git push heroku master

Not sure where you are in the process. You also don't need github to deploy on heroku, just git. Hope this helps!

---

First, make sure you're logged into heroku:

heroku login 

Enter your credentials.

It's common to get this error when using a cloned git repo onto a new machine. Even if your heroku credentials are already on the machine, there is no link between the cloned repo and heroku locally yet. To do this, cd into the root dir of the cloned repo and run

heroku git:remote -a yourapp

---

Following official Heroku article:

Initialize GIT

$ cd myapp
$ git init

$ git add .
$ git commit -m "my first commit"

Then create (initialize) heroku app with:

$ heroku create YourAppName

Lastly add git remote:

$ heroku git:remote -a YourAppName

Now you can safely deploy your app with:

$ git push heroku master

You should wait for some time and see if you don't get any error/interrupt on console while deploying. For details look at heroku article.

---

You forgot to link your app name to your heroku. It's a very common mistake. if your app is not created, then use:

heroku create (optional app name)

else:

git add .
git commit -m "heroku commit"

heroku git:remote -a YOUR_APP_NAME

git push heroku master

---

heroku git:remote -a YourAppName

---

Follow this steps:

$ heroku login

Create a new Git repository Initialize a git repository in a new or existing directory

$ cd my-project/
$ git init
$ heroku git:remote -a appname

Deploy your application Commit your code to the repository and deploy it to Heroku using Git.

$ git add . 
$ git commit -am "make it better"
$ git push heroku master

Existing Git repository For existing repositories, simply add the heroku remote

$ heroku git:remote -a appname

---

Might be worth checking the config file in the .git folder. If the heroku parameters are missing then you´ll get this error heroku param

[remote "heroku"]
    url = git@heroku.com:`[Your heroku app].git
    fetch = +refs/heads/*:refs/remotes/heroku/*

the .git folder should be in the local computer file directory for the app you created in heroku. e.g C:\Users\You\Your app.git

Hope this helps

---

If this error pops up, its because there is no remote named Heroku. When you do a Heroku create, if the git remote doesn’t already exist, we automatically create one (assuming you are in a git repo). To view your remotes type in:

“git remote -v”. # For an app called ‘appname’ you will see the following:

$ git remote -v
heroku git@heroku.com:appname.git (fetch)
heroku git@heroku.com:appname.git (push)

If you see a remote for your app, you can just “git push master” and replace with the actual remote name.

If it’s missing, you can add the remote with the following command:

git remote add heroku git@heroku.com:appname.git

If you’ve already added a remote called Heroku, you may get an error like this:

fatal: remote heroku already exists.

so, then remove the existing remote and add it again with the above command:

git remote rm heroku

Hope this helps…

My problem was that I used git (instead of heroku git) to clone the app. Then I had to:

git remote add heroku git@heroku.com:MyApp.git

Remember to change MyApp to your app name.

Then I could proceed:

git push heroku master

---

show all apps heroku have access with

heroku apps

And check you app exist then

 execute heroku git:remote -a yourapp_exist

---

For me the answer was to cd into the root directory of the app before running heroku create or git push heroku master

---

Type heroku create then git push heroku master (this is after creating a repository with 'git init' and committing the project)

---

I encountered the same error making a much more novice mistake: I was typing in Heroku with a capital "H," instead of lowercase.

I recognize that's certainly not the solution for everyone who encounters this error, but it was in my case.

---

I got the same error and it turned out I was in the wrong directory. It's a simple mistake to make so double check that you are in the root and then run heroku create and heroku git push master again. Of course you must have done git init, as mentioned in StickMaNX answer above, already before the heroku steps.

---

Run this

heroku create

before pushing your code.

---

I had the same issue, but later I found out that I forgot to create an app before deploying it. Try the following steps in terminal.

heroku login
heroku create

I am just learning heroku and often forget the steps so I wrote an article about it. You can find it here: https://medium.com/@saurav.panthee/deploy-flask-app-to-heroku-under-3-minutes-2ec1c0bc403a

---

I've seen all the answers here and the only thing missing is after going through these steps:

$ git add .
$ git commit -m "first heroku commit"

You should run the command below:

$ heroku git:remote -a <YourAppNameOnHeroku>

And lastly, run this:

$ git push -f heroku <NameOfBranch>:master

Notice I used because if you're currently in a different branch to master it would still throw errors, so If you are working in master use master, else put the name of the branch there.

---

On the site:

https://dashboard.heroku.com/apps/**<YourAppNameOnHeroku>**/deploy/heroku-git

steps are described.

---

For those who are trying to get heroku to work on codeanywhere IDE:

heroku login
git remote add heroku git@heroku.com:MyApp.git
git push heroku

---

I had to run the Windows Command Prompt with Administrator privileges

---

The following commands will work well for ruby on rails application deployment on heroku if heroku is already installed on developers machine. # indicates a comment

heroku login heroku create heroku keys:add #this adds local machines keys to heroku so as to avoid repeated password entry git push heroku master heroku rename new-application-name #rename application to the preferred name other than the auto generated heroku name

---

In my case, I was already logged-in and I just executed git push.

---

i forgot to create a domain name before running git push heroku main. Creating a domain name resolved the problem.
