javascript - grunt 找不到 compass 命令。为什么不？

Question

我正在尝试使用 grunt 和 yeoman 在 CentOS 7 上设置一个 node.js 服务器，但我收到一条错误消息说 compass找不到命令。我读了this other posting about a similar error ，但另一篇文章假设您正在使用 ruby​​ on rails，而我不是。另外，the methods that I am testing come from this tutorial , 当我到达教程中说输入 grunt serve. 的那一点时，事情就停止了。我已经对教程进行了一些补充，以一一解决错误消息，但目前关于 compass 的错误似乎没有谷歌可用的答案。

我需要执行哪些具体步骤才能让 grunt 能够找到并使用 compass ？

这是导致 grunt serve 的当前错误失败:

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，我切换到非根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命令导致以下完整错误输出:

[user@localhost client]$ grunt serve

请注意，当我尝试运行 grunt serve 时会返回相同的错误消息作为根代替。 那么需要采取哪些具体步骤来解决这个错误呢？

Answer 1

我以为 compass 是 ruby 的东西。

试试gem install compass

对于基于 yum 的系统

yum -y install gcc ruby​​-devel ruby​​gems compass 也可能有效。
