4）在Gemfile中： gem'twitter-bootstrap-rails'，：git =＆gt; 'git的：//github.com/seyhunak/twitter-bootstrap-rails.git'

5）捆绑安装

6）rails生成bootstrap：少安装

7）浏览器：

重启后

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any styles
 * defined in the other CSS/SCSS files in this directory. It is generally better to create a new
 * file per style scope.

// @link-color: #ff0000;
