railscasts.com是著名的Rails视频播客网站，大概每周出一期节目。从2007年3月份至今已经出了270多集，作者Ryan Bates (rbates on Twitter and ryanb on GitHub)持之不懈的工作着实让人钦佩。我也是陆陆续续看过一些，今日再次光顾railscasts.com网站，发现已经改版，令人欣喜的是其About介绍页里也提供了源代码的链接，细看时发现已经升级到Rails3了，一时手痒决定安装测试下。下面是安装测试过程：
1、前提
RVM、Ruby1.9.2已经安装。由于我的虚拟机在早前就已经安装了Rails3的环境，此处也就略去了。需要的同学可搜索相关文章。
2、下载：使用git工具
代码仓库地址：https://github.com/ryanb/railscasts
$ cd projects
$ git clone https://github.com/ryanb/railscasts.git
3、安装
3.1 生成配置文件，执行"script/setup"。
3.2 安装项目依赖gem包：
首先安装bundler，然后使用bundler自动安装其它依赖包。
Ubuntu@ip-10-48-111-136:~/projects/railscasts$ gem install bundler Successfully installed bundler-1.0.15 1 gem installed

4、配置
主要是修改config/database.yml文件中的数据库用户名与口令。
5、运行
