咕噜不能find指南针命令。 为什么不？
我正在尝试在CentOS 7上使用grunt和yeoman来设置node.js服务器，但是我收到一个错误，指出无法findcompass命令。 我读了另一篇关于类似错误的文章 ，但另一篇文章假设你在rails上使用ruby，而我并不这样做。 另外， 我正在testing的方法来自于本教程 ，当我在教程中指出要inputgrunt serve.时，事情就停止了grunt serve. 我已经做了几个补充教程，以逐一解决错误消息，但目前关于指南针的错误似乎没有谷歌答案。
我需要采取哪些具体步骤才能find并使用指南针？
这里是目前的错误导致grunt serve失败：
Warning: Running "compass:server" (compass) task Warning: Command failed: /bin/sh -c compass --version /bin/sh: compass: command not found Use --force to continue. Aborted due to warnings.
这是导致这个问题的一系列命令：
首先，我以root身份执行了以下安装命令：
yum install -y nodejs yum clean all && yum update yum install -y gcc-c++ openssl-devel make npm install -g express npm install -g express-generator npm install -g yo npm install -g generator-angular npm install -g bower npm install -g nodemon npm install -g grunt-cli npm install generator-karma npm install -g compass npm install -g grunt-contrib-compass
接下来，我切换到非root用户帐户，并运行以下命令：
cd /home/user/angular_apps mkdir /home/user/angular_apps/my_new_project && cd /home/user/angular_apps/my_new_project mkdir /home/user/angular_apps/my_new_project/client // will house angular and app code mkdir /home/user/angular_apps/my_new_project/server // will house node and express code, among other things cd /home/user/angular_apps/my_new_project/client yo angular // get yeoman to scaffold out the front end // yeoman asked many questions. I said no to replacing grunt with anything else and I said yes to every other include npm install // this will install all the required packages bower install // this will hook up bower and thus prevent a downstream error grunt serve
grunt serve命令会导致以下完整的错误输出：

请注意，当我尝试以root身份运行grunt serve时，会返回相同的错误消息。 那么需要采取哪些具体措施来解决这个错误呢？
我以为指南针是一个ruby的东西。
尝试gem install compass
对于基于yum的系统
yum -y install gcc ruby-devel rubygems compass也可能工作。
