heroku push error: “Could not detect rake tasks”

Question

I\'m trying to deploy a basic app and it\'s not working. Using

git push heroku master 

I got this error message:

remote:          


        

Answer 1

TL;DR; Have gem "better_errors", gem "binding_of_caller", gem 'pry-byebug' in global scope of your Gemfile

In my case it was because I moved these 3 gems from the global scope to development in my Gemfile:

gem "better_errors"

gem "binding_of_caller"

gem 'pry-byebug'

They should probably be only in the development scope, but there's something that I'm missing. So, moving them back outside of the development scope my deploy and rakes work correctly
