Question

In EY AppCloud, even when you run in development env, they run bundler –without development and test. My Gemfile contains this

group :test, :development do
  gem 'ruby-debug19', :require => 'ruby-debug'
end

and when I deploy I get this error:

If I comment out the gem ‘ruby-debug19’ line in Gemfile it works. But it should be ignoring that anyway since as mentioned, AppCloud ignores test, development env gems. It works locally in both cases. Can anyone think at all what might cause this?

Answer 1

I believe this is because config/application.rb calls Bundler.require with a few group names, one being Rails.env. You RAILS_ENV on the command line is development, which means Bundler.require is trying to load the development group and require things in it, including ruby-debug. Since the bundle has been installed the development group, it breaks.

Probably best to use development for RAILS_ENV when running your app locally and either staging or production for your app on AppCloud.
