sass - 编译 sass 时出现代码包错误

Question

Compass 无法编译项目中的一个或多个文件：

/Library/Ruby/Gems/2.0.0/gems/compass-1.0.1/lib/compass/commands.rb:14:in `<top (required)>': undefined method `discover_extensions!' for Compass:Module (NoMethodError)
    from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from /Library/Ruby/Gems/2.0.0/gems/compass-1.0.1/lib/compass/exec.rb:7:in `<top (required)>'
    from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from /Applications/CodeKit.app/Contents/Resources/engines/compass/compass/bin/compass:43:in `block in <main>'
    from /Applications/CodeKit.app/Contents/Resources/engines/compass/compass/bin/compass:30:in `fallback_load_path'
    from /Applications/CodeKit.app/Contents/Resources/engines/compass/compass/bin/compass:41:in `<main>'

当我尝试编译 sass 文件时，看看上面那个 codekit 给我的错误。我有最新版本的 sass（Sass 3.4.1）和指南针（Compass 1.0.1）我不知道为什么它给我这个错误。

有任何想法吗？提前致谢。
