我通过gem install compass安装指南针
C:\Users\XXXXXX\Desktop\project\webfeature>gem install compass
Fetching: sass-3.2.19.gem (100%)
Successfully installed sass-3.2.19
Fetching: compass-0.12.6.gem (100%)
Successfully installed compass-0.12.6

看起来不错，不是吗？ 但是当我试图通过带有“grunt dev”的gruntjs运行它时它不起作用，说它无法加载文件sass_extensions.rb，尽管它正好在那里......
Running "compass:dev" (compass) task
LoadError on line ["55"] of C: cannot load such file -- src/sass/libs/sass_extensions.rb
有什么问题？
