compass以外还有一个很实用的scss模块，
_media-queries.scss通过终端下载
curl -O https://raw.github.com/paranoida/sass-mediaqueries/master/_media-queries.scss凡是用compass编译就可以直接import compass的模块，但是不主张import "compass",理由如下：
http://blog.rocodev.com/posts/11-dont-import-compass
禁止使用
@import "compass";，最少最少都要從第二層如@import "compass/css3";呼叫起。上禮拜幫一個專案上了從 Wrapbootstrap 上買來的 Core Admin CSS 當後台 Admin 之後。開發的同事偷偷問我，是否有什麼設定可以讓開發時不重新 compile CSS，因為現在第一次進後台，compile CSS 都要超過五秒。但我們自己寫的前台 CSS 倒沒有這個問題....
五秒是個很驚人的數字，根據以往的經驗，我猜測可能又是 CSS 架構設計不當的問題，所以編譯才要花這麼久時間。
果不其然，鑽進去看了一下整體架構之後，我只送了一個 commit，改了九行。
如果要在只有sass没有compass的情况下使用compass模块
* reset * css3 * layout * typography * utilities
需要从github下载compass的源文件，从
解压出来叫compass-stableframeworkscompassstylesheetscompass
抽取compass文件夹，放到自己的sass目录下
然后用sass --watch命令。

在rails下面创建compass项目
rails new texttextnamefoldername
最好加上参数
rails new texttextnamefoldername --skip-bundle （这样不会卡在那里需要ctrl+c）
vi gemfile
vim gemfile
//没找到vi只好去sublime Text里面左侧选择
gem list | grep compass
bundle
rails generate scaffold texttextnamefoldername
rake db:migrate
rails s
//这里并没有使用compass的创建，因为并不需要遵循它的结构
create compass namenamename
在创建好的rails项目的gemfile里面加上compass
如果没有加载sass还要在尾部加上gem 'sass-rails'
