Rails 4 - cannot load such file -- rich (LoadError) - After removing gem from gemfile

Question

I've removed a gem from my gemfile (specifically this gem). I've run bundle update. I can't start the server or migrate db because of this error I now get: /lib/active_support/dependencies.rb:229:in `require': cannot load such file -- rich (LoadError)

Answer 1

I've had trouble removing this gem as well. Simply run a search in your application to find all references to the gem and remove them. Unfortunately I wasn't able to find any other way other than manual removal.
