I am trying to push my app to heroku and I get the following message:
$ heroku create
Creating electric-meadow-15..... done
Created http://electric-meadow-1
I was getting the second error you posted "failed to push some refs to 'git@heroku.com:floating-stone-94.git' " (with a different app name) and i got rid of it by doing the following:
git remote rm heroku
heroku create
you should see a line that says 'Git remote heroku added'. Also
git remote -v
should now have the correct app.
Type this and I think you'll see the problem:
git remote -v
Fix it like this:
git remote rm heroku
git remote add heroku git@heroku.com:electric-meadow-15.git
If you got here and think you have a similar problem but all of the other stuff suggested does not work you might want to try:
heroku restart
For all the people who this does not work, check your ~/.heroku/credentials
If the email or token does not match the account, you won't see your apps.
