When I am running server its throwing error shown in logs below. I googled a lot but didn\'t get reason behind it. Somebody please put some light on it.

Gemfile

Answer 1

I had the same problem when trying to use ActionCable with Rails 4.2.5 and the solution was to add the following to config/application.rb:

config.autoload_paths += %W(#{config.root}/app/channels)

This is with the ActionCable gem:

gem 'actioncable', github: 'rails/actioncable', branch: 'archive'
