When I try to push my app to Heroku I get this response:
fatal: 'heroku' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
I have tried 'heroku keys:add' but still comes up with the same result. I already have an ssh key for my GitHub account.
To add a Heroku app as a Git remote, you need to execute heroku git:remote -a yourapp
.
