1、下载 Ruby 点击 Windows installer 下载并安装在 我用的是Ruby1.9.3 最新版的
地址：http://rubyonrails.org/download
2、下载 RubyGems 选择ZIP格式，用它来更新一些支持文件
地址：http://rubygems.org/pages/download
3、下载 Aptana Studio 3 并安装
网址：http://www.aptana.com/products/studio3
4、Ruby 安装完成后 运行CMD ruby -v 后出现当前装的ruby的版本号 说明ruby安装好了
c:\>ruby -v
ruby 1.9.3p194 (2012-04-20) [i386-mingw32]
5、下面我们来安装 RubyGems
解压刚才下载的rubygems-1.8.24.zip 在CMD下 cd 到 rubygems-1.8.24 里 执行 ruby setup.rb
c:\>ruby setup.rb #执行完后 我们看一下rubygems当前版本
c:\>gem -v
1.8.24
这样我们的RubyGems 就安装完成了
6、下面我们安装Rails
c:\>gem install rails
这个过程可能会慢一点。会下载N个包，直到Rails安装完毕，完毕后我们看一下版本号
c:\>rails -v
Rails 3.2.3
7、基本的ruby on rails 安装完成了。但是当我们运行Aptana Studio 3 并建立工作。在 Aptana Studio 3 -> new -> Rails Project 我们先生成一个demo工程Name 处我们输 demo 点击完成 会看到如下信息Administrator@QN1M0CLRBS5FHRU ~/My Documents/Aptana Studio 3 Workspace/demo $ rails new . exist create README.rdoc create Rakefile create config.ru create .gitignore create Gemfile create app create app/assets/images/rails.png create app/assets/javascripts/application.js create app/assets/stylesheets/application.css create app/controllers/application_controller.rb create app/helpers/application_helper.rb create app/mailers create app/models

Please update your PATH to include build tools or download the DevKit from 'http://rubyinstaller.org/downloads' and follow the instructions at 'http://github.com/oneclick/rubyinstaller/wiki/Development-Kit' An error occured while installing json (1.7.3), and Bundler cannot continue. Make sure that `gem install json -v '1.7.3'` succeeds before bundling.
我们会看到缺少 json 并提示我们安装 但是呢。他给的这两个同址 我是打不开 我们到其它地方下载地址：https://github.com/oneclick/rubyinstaller/downloads/选择DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe — DevKit-4.5.2 self extracting archive这个文件约有20M 下载完成后解压至c:\dk\位置 我们在CMD下安装c:\dk>ruby dk.rb init
c:\dk>ruby dk.rb review
c:\dk>ruby dk.rb install
8、我来启动一下刚才生成的demo 工程
Administrator@QN1M0CLRBS5FHRU ~/My Documents/Aptana Studio 3 Workspace/demo $ rails s Could not find gem 'jquery-rails (>= 0) x86-mingw32' in the gems available on this mach [0m Run `bundle install` to install missing gems.
出现错误。提示我们要运行demo工作sever 服务，还需要安装一些插件来支持rails 服务运行。

以上蓝色的 安装完后。在Aptana Studio 3 运行 rails s会提示
$ rails s => Booting WEBrick => Rails 3.2.3 application starting in development on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server [2012-05-14 13:04:23] INFO WEBrick 1.3.1 [2012-05-14 13:04:23] INFO ruby 1.9.3 (2012-04-20) [i386-mingw32] [2012-05-14 13:04:23] INFO WEBrick::HTTPServer#start: pid=964 port=3000
自此我们的ruby on rails 已经配置完成了但是我们为了更完美一些还要安装一个rdocc:\>gem install rdoc-data
c:\>gem install ruby-debug-ide
