[1v]

When adding gem to gemfile:

gem 'twitch-chat', :require => 'twitch/chat'

I have this error when starting server:

Finally got it working! See my changes https://github.com/EnotPoloskun/twitch-chat/compare/master...1v:master

And in Gemfile I added just:

gem 'twitch-chat'

So, should we close this issue?
