sass - 'grunt compass' 抛出它不在系统路径中的错误

Question

我对使用 grunt、compass 和 sass 很陌生，并且无法使其正常工作。我使用 Drupal 7 安装了 Redhat，当我尝试从站点的主题目录中运行“grunt compass”时，出现以下错误:

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 gem。当我运行“ gem 列表”时，我得到以下信息:

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 gem 。然后我通过“echo $PATH”查看了我的 PATH 设置并得到以下信息:

/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，发现在/usr/bin 中有 ruby​​2.0，在/home/ec2-user/bin 中有 compass，所以安装似乎在系统 PATH 中。

当我从命令行运行“ruby2.0”时，我得到以下信息:

from <internal:abrt_prelude>:2:in `<compiled>'

当我简单地运行“ ruby ”时，什么也没有发生。 'grunt compass' 是否正在寻找 'ruby' 而我有 'ruby2.0'？我需要用 ruby​​ -> ruby​​2.0 创建一个符号链接(symbolic link)吗？

当我从命令行运行“指南针”时，我得到:

用法:指南针帮助[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.

等等。

任何想法将不胜感激

Answer 1

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 安装了带有 Ruby 和 Compass 的 Windows 版本，请尝试；

控制面板 > 系统 > 高级系统设置

高级 > 环境变量

在系统变量下搜索“路径”变量，其值应为

最后点击编辑添加;C:\Ruby193\bin在变量值的最后。

这应该可以解决问题。

请注意 ;C:\Ruby193\bin指在你的机器上安装 Ruby > Compass。

如果你有一个 Mac 版本，那么类似的修复版本可能适用于 Mac，但我无法为你映射，谷歌搜索可能会有所帮助......
