安装rvm后无法运行指南针

Question

I installed RVM yesterday and now I can't run Compass, I get the following error.

compass watch skin/frontend/default/default/
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:296:in `to_specs': Could not find 'compass' (>= 0) among 13 total gem(s) (Gem::LoadError)
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:307:in `to_spec'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_gem.rb:47:in `gem'
    from /usr/local/bin/compass:22:in `<main>'

I guess I need to update my compass and/or sass config? But I'm not sure how.

$ which -a gem
/Users/holy/.rvm/rubies/ruby-2.3.0/bin/gem
/usr/bin/gem

Answer 1

最后，我只是将RVM设置为使用系统Ruby，而Compass再次起作用，命令是：

rvm use system

Answer 2

have tried reinstalling sass and compass ? Sorry for the probably obvious answer
