Compass and Susy require a different version of Sass
问题 I am working on my website and I want to use Susy as well as Compass. I am using Grunt too. When I run my grunt task I get this error: Denniss-MacBook-Pro:portfolio dennis$ grunt --trace Running "compass:dev" (compass) task Gem::LoadError on line ["1990"] of /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/specification.rb: Unable to activate susy-2.1.1, because sass-3.2.17 conflicts with sass (~> 3.3.0) Run with --trace to see the full backtrace Warning: ↑
