Issue when upgraded to Rails 4 (class attributes)

[anlek]

It seems this is something to do with the tilt gem (version 1.4). To fix it, you can add this to your Gemfile:

gem 'tilt', '~> 1.3.6'

It's not only in rails 4. If you add gem 'slim-rails' , 1.0.3 get installed and slim version is 1.0.1.

To fix you can add:

gem 'slim-rails', '~> 1.1'

This should be fixed with newest slim 1.3.9
