Q:

heroku : run rake db:migrate error

Running `rake db:migrate` attached to terminal... failed
 !    Multiple apps in folder and no app specified.
 !    Specify app with --app APP.

I get the above error in my terminal when I try to run rake db:migrate can anyone please help?

A:

As the error clearly states, you need to specify which app you wish to run the command for. If you are inside of the project directory, you shouldn't need to specify the app. If you are outside of your projects folder run the command like so:
heroku run rake db:migrate --app <your-app-name>
