This is an issue with sass-rails and/or sprockets: rails/sass-rails#191, sstephenson/sprockets#537

[tonycoco]

For now, just add this to your Gemfile...

gem "sass-rails", "4.0.2"

Or, until those issues referenced above get fixed.

@tonycoco this has been fixed on master: 04aef93

@seanlinsley, the problem is not in sprockets. ActiveAdmin should probably lock sass-rails and not sprockets, for now. See @josh's (sprockets maintainer) comments...

"This is a sass-rails issue. It monkey patches private Sprockets classes. The fix will need to be made there."

Though, locking sprockets fixes the problem, we should probably just lock sass-rails and leave sprockets alone...

gem "sass-rails", "4.0.2"

Anyone else have any more information on the topic?

[josh]

@tonycoco sound advice.

[cookrn]

Was having this issue today. To fix, I locked:

gem 'rails', '4.0.4'
gem 'sass-rails', '~> 4.0.3'
gem 'bourbon', '< 4'
gem 'activeadmin', :github => 'gregbell/active_admin'

Please let me know if I can provide additional information.

This looks to be resolved now 🐝
