TLDR: lock sprockets to 2.11.0 or sass-rails to 4.0.2
After upgrading our Rails 4 apps to the latest minor release, I got this error every single time:
ArgumentError - wrong number of arguments (2 for 1) (in /profiles/swi/Projects/portal/app/assets/stylesheets/style.css.sass): sprockets (2.12.0) lib/sprockets/sass_importer.rb:11:in `initialize' compass-rails (1.1.6) lib/compass-rails/patches/sass_importer.rb:7:in `block in evaluate' compass-rails (1.1.6) lib/compass-rails/patches/sass_importer.rb:7:in `evaluate' () profiles/swi/.rvm/gems/ruby-2.0.0-p195@global/gems/tilt-1.4.1/lib/tilt/template.rb:103:in `render' sprockets (2.12.0) lib/sprockets/context.rb:197:in `block in evaluate' sprockets (2.12.0) lib/sprockets/context.rb:194:in `evaluate' sprockets (2.12.0) lib/sprockets/processed_asset.rb:12:in `initialize' sprockets (2.12.0) lib/sprockets/base.rb:374:in `block in build_asset' sprockets (2.12.0) lib/sprockets/base.rb:395:in `circular_call_protection' sprockets (2.12.0) lib/sprockets/base.rb:373:in `build_asset'
At first, looking into the referenced stylesheet, I could not find anything wrong, so I upgraded several gems. I got it working with this configuration:
gem 'compass-rails', "~> 1.1.6" # not relevant for this case, gem 'sass-rails', '4.0.2' gem 'sprockets', '~>2.11.0'
Some people already reported this issue on the Sprockets issue tracker.
