windows下安装ruby on rails

1.首先去 http://rubyforge.org/frs/?group_id=167 找一个One-Click Ruby Installer下载下来
2.安装One-Click Ruby Installer的时候我是选择默认选项来安装的。

运行 ruby -v 显示版本号，表示安装成功。否则自行添加系统变量

SET RUBY_HOME=D:/ruby
SET PATH=%PATH%;%RUBY_HOME%/bin
SET RUBYOPT=rubygems

把以上代码复制到记事本，另存为ruby.bat 然后执行。

3.安装Rails：
(1) 远程安装：
运行 gem install rails --include-dependencies，安装Rails（需要连接网络）。

(2) 本地安装：

3.2.1. Rails 需要依赖下面几个库，而且版本依赖很严格（本来想装2.0.2的，可惜有两个包不支持，没有办法，只能装1.2.6了），分别去 http://rubyforge.org/frs/?group_id=307 去下载rails (我下载的是1.2.6版本)； http://rubyforge.org/projects/activesupport 去下载activesupport(我下载的是1.4.4版本)； http://rubyforge.org/projects/activerecord/ 去下载activerecord(我下载的是1.15.6版本)； http://rubyforge.org/projects/actionpack 去下载actionpack(我下载的是1.13.6版本)； http://rubyforge.org/projects/actionmailer 去下载actionmailer(我下载的是1.3.6版本)； http://rubyforge.org/projects/aws 去下载actionwebservice(我下载的是1.2.6版本)； http://rubyforge.org/projects/rake 去下载rake(我下载的是0.8.1版本)；
以上所有下载文件都包括zip和gem;

3.2.2.把第三步中下载的所有文件放到一个目录中，比如我把它放在了D:/rails中；
5.打开cmd，进入D盘

C:/Documents and Settings/Administrator>d:

D:/>cd rails

D:/rails>gem install activesupport-1.4.4.gem （同等效果的D:/rails>gem install activesupport -v 1.4.4）
