当我尝试运行 rspec 或 autotest 时，我不断收到错误消息：
/Users/Craig/.rvm/gems/ruby-1.9.2-p136/gems/sass-3.1.0.alpha.249/lib/sass/plugin.rb:35:in `<module:Plugin>': uninitialized constant Sass::Util (NameError)
从我的 Gemfile 中删除 sass 后，规范运行良好。
有没有办法告诉 rspec 忽略 gem？或者我该怎么做才能运行 rspec/autotest？为什么 rspec 仍然依赖 Gemfile 来运行？rake spec 工作正常，但运行 rspec /file/path 或 autotest 不行。
我的 gemfile 看起来像这样：
