我想我会尝试使用 SASS，但即使安装它也遇到了问题（在 Bluehost 共享主机上，它不完全是 Ritz）。
这是我检查它是否安装的结果：
username [~/public_html/sites/all/themes]# sass -v
Sass 3.2.7 (Media Mark)
username [~/public_html/sites/all/themes]# compass -v
Unable to load Sass. Please install it with one of the following commands:
gem install sass --pre
/usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require': no such file to load -- sass (LoadError)

from /home7/username/ruby/gems/gems/compass-0.12.2/bin/compass:19
我尝试卸载，以不同的顺序重新安装，按照错误消息中的建议使用 --pre 标志安装 Sass，自行安装 compass 并让 sass 由 compass 安装，结果相同。
我还没有使用这些工具，所以我不知道会发生什么，但我确实必须更新我的 $PATH 才能让“sass”之类的命令正常工作，所以我怀疑 compass 无法找到 sass 或某物。发帖希望这对于有经验的人来说是一个明智的选择。
