grunt 找不到罗盘命令。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，提示无法找到 compass 命令。我读了 , but the other posting assumes you are using ruby on rails, which I am not. Also, the methods that I am testing come from this tutorial，当我读到教程中说要输入 grunt serve. 的地方时，一切都停止了。关于指南针的错误似乎没有 google 可用的答案。

我需要采取哪些具体步骤才能让 grunt 能够找到并使用指南针？

这是导致 grunt serve 失败的当前错误：

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.

这是导致此问题的一系列命令：

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执行以下命令：

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，当我以 root 身份尝试运行 grunt serve 时，会返回相同的错误消息。 那么需要采取哪些具体步骤来解决这个错误？

Answer 1

我以为罗盘是 ruby 东西。

尝试gem install compass

对于基于 yum 的系统

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

grunt 找不到罗盘命令。为什么不？

grunt cannot find compass command. Why not?

javascript

node.js

angularjs

gruntjs

compass
