Angularjs grunt服务因yeoman mean中的警告而中止

我在遵循mean.io的教程，在其中，我必须安装

yo

过了一段时间，一切都安装好了，最后我不得不运行“咕噜服务”

然后出现此错误/警告

我遵循了这个教程

使用此命令运行时出现Ans

grunt service--force

我得到了所需的页面@htttp://localhost/9000/#/ 不带任何样式的页面

您需要安装。它由SASS使用，SASS包含在角形耶曼发生器中

如果您安装了ruby，您可以这样做

gem install compass

永远不要使用——强制。它并不适用于所有情况，但grunt会针对每个错误/警告（致命错误除外）抛出它。

thaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaazzzzzzzzzzzin Ubuntu，甚至没有安装Ruby：

sudo-apt-get-install-Ruby-compass

sudo-gem-install-compass

如果您不是root/admin，您将收到您没有权限的警告。
