1. Install Ruby
http://rubyinstaller.org/downloads/
我習慣把開發的環境建置在 D:\Develop\

2. Update Ruby
開啟命令提示字元

D:
cd Develop\Ruby200-x64
gem update --system

3. Install Sass
* Standard Gem

gem install sass

* Prerelease Gem

gem install sass --pre

4. Install compass

gem install compass

5. Install susy

gem install susy

6. Create Projcet

compass create <project name> -r susy -u susy

7. Execute

compass watch

這邊我強烈建議使用console，如果使用其他的套件或工具常常會詭異的發生下面的錯誤

LoadError on line xxx of xxx.file: no such file to load -- susy
