我很擅长使用grunt，指南针和sass，并且无法使用它。我有一个使用Drupal 7的Redhat安装，当我尝试从站点的主题目录中运行'grunt compass'时，我收到以下错误：
Running "compass:dist" (compass) task
Warning: You need to have Ruby and Compass installed and in your system PATH for this task to work. More info: https://github.com/gruntjs/grunt-contrib-compass Use --force to continue.
Aborted due to warnings.
我已经安装了Grunt，Bower，并使用'bundle install'来安装所需的宝石。当我运行'gem list'时，我得到以下内容：
bigdecimal (1.2.4)
breakpoint (2.0.7)
bundler (1.6.2)
bundler-unload (1.0.2)
chunky_png (1.3.1)
compass (0.12.6)
compass-normalize (1.4.3)
executable-hooks (1.3.1)
fssm (0.2.10)
gem-wrappers (1.2.4)
io-console (0.4.2)
json (1.8.1)
kss (0.5.0)
minitest (4.7.5)
psych (2.0.3)
rake (10.1.0)
rdoc (4.1.0)
ruby (0.1.0)
rubygems-bundler (1.4.3)
rubygems-update (2.2.2)
rvm (1.11.3.9)
sass (3.2.19)
test-unit (2.1.1.0)
zurb-foundation (4.3.2)
所以看来我拥有所有需要的宝石。然后我通过'echo $ PATH'查看了我的PATH设置，得到了以下内容：
/home/ec2-user/.rvm/gems/ruby-2.1.1/bin:/home/ec2-user/.rvm/gems/ruby-2.1.1@global/bin:/home/ec2-user/.rvm/rubies/ruby-2.1.1/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/opt/aws/bin:/home/ec2-user/bin:/home/ec2-user/.rvm/bin
我查看了路径并看到在/ usr / bin中我有ruby2.0并且在/ home / ec2-user / bin我有指南针所以安装似乎在系统路径中。
当我从命令行运行'ruby2.0'时，我得到以下内容：

当我简单地跑'红宝石'时，什么都没有发生。 'grunt指南针'是否正在寻找'红宝石'，而我却拥有'ruby2.0'？我是否需要使用ruby创建符号链接 - ＆gt; ruby2.0？
当我从命令行运行'compass'时，我得到：
用法：指南帮助[命令]
Description:
The Compass Stylesheet Authoring Framework helps you
build and maintain your stylesheets and makes it easy
for you to use stylesheet libraries provided by others.
等
任何想法都将不胜感激

我已经对此进行了一些研究，以下内容对我有用......
如果您通过CLI安装了Ruby和Compass的Windows版本，请尝试;
;C:\Ruby193\bin。这应该可以解决问题。
请注意;C:\Ruby193\bin指的是Ruby＆gt;的安装。指南针在你的机器上。
如果您有Mac版本，那么类似版本的修补程序可能适用于Mac，但我无法为您映射，谷歌搜索可能会有所帮助......

grunt compass寻找红宝石宝石。在你的情况下'罗盘-v'没有错误，所以指南针部分工作正常。除此之外，它不依赖于红宝石的任何其他组成部分。
现在指南针准备就绪，grunt compass还会查找npm模块grunt-contrib-compass，您可以在package.json文件中找到它。如果您执行了npm install这个npm包已安装，我相信它应该使grunt compass正常工作。

grunt-contrib-compass有一个发出魔法的bundleExec选项。使用bundle，它将加载使用bundle install安装的gem。只需设置bundleExec：true
即可
