咕嚕聲找不到羅盤命令。 為什么不？

Question

我正在嘗試使用grunt和yeoman在CentOS 7上設置node.js服務器，但是我收到一條錯誤，指出無法找到compass命令。 我讀了另一篇關於類似錯誤的帖子，但另一篇帖子假設你在rails上使用ruby，我不是。 此外， 我正在測試的方法來自本教程 ，當我在教程中指出鍵入grunt serve.時，事情就會停止工作grunt serve. 我已經為教程做了一些補充，逐一解決錯誤消息，但是關於指南針的當前錯誤似乎沒有google-able的答案。

我需要采取哪些具體步驟才能使咕嚕聲能夠找到並使用指南針？

以下是導致grunt serve失敗的當前錯誤：

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.

以下是導致此問題的一系列命令：

首先，我以root身份執行了以下安裝命令：

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  

接下來，我切換到非root用戶帳戶並運行以下命令：

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命令導致以下完整錯誤輸出：

[user@localhost client]$ grunt serve

請注意，當我嘗試以root身份運行grunt serve時，會返回相同的錯誤消息。 那么需要采取哪些具體步驟來解決此錯誤？

Answer 1

我認為指南針是紅寶石的東西。

嘗試gem install compass

對於基於百勝的系統

yum -y install gcc ruby-devel rubygems compass也可以。
