对于特定错误Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:9000/styles/style.css，您还应该检查您是否安装了compass 服务器。那就是：

gem install compass

要检查 compass 是否正常运行，请运行 grunt serve --verbose 并检查输出是否有任何错误，例如：

in `to_specs': Could not find compass (>= 0) amongst [...] (Gem::LoadError)

脚手架搭建完成后，您必须运行命令bower install 和npm install 来安装所需的包（在bower.json 和package.json 文件中描述。之后，grunt 将能够提供依赖关系。

当您构建项目并使用引入新的依赖项时，您将通过编辑 bower.json 和/或 package.json 文件并重新运行安装来添加它们。下载的包通常不存储在源代码管理中。
