Bundler.require leads to uninitialized constant ActionController::Base

[gmassman]

I recently installed the gem gush in my rails 5.1.6 app. After running bundle exec gush I get the following stack trace.

garrett:pesto ~/workspace/web-api> bundle exec gush                                                                                                                                               <-  4:32PM

It looks to me like ActionController isn't loaded at runtime, but including the action_controller or actionpack dependencies in the gemspec doesn't seem to help anything.

Anyone have an idea about what's going on here?

@gmassman you can check an alternative

@gmassman - I added a note in README to add gem 'health_check' after the rails gems - I presume you did that?
