So I have a Rails application that I am trying to push to Heroku. When I run git push heroku master, I get:

$ git push heroku master

I have tried the solutions found on this question, but nothing works (I get the same error). Everything runs fine on my local machine, so I don’t know why it is not working on Heroku.

I do also want to ask: Are you supposed to run the commands found on this question from your local server, or from the heroku shell for your app? Because I have tried running the commands from the heroku shell but to no avail:

$ heroku run bash --app *****
Running bash on ⬢ *****... up, run.4316 (Basic)
~ $ bundle install
bash: bundle: command not found
