下载ruby的windows版本的安装程序，下载地址：http://rubyforge.org/frs/?group_id=167或者http://files.rubyforge.vm.bytemark.co.uk/rubyinstaller/
下载exe版本的ruby，我下载的是rubyinstaller-1.9.3-p327.exe，有人说ruby1.9.3版本的不稳定，建议用ruby1.8.6版本的，也不知道哪里不稳定，就捡这个版本用吧， 187、192、193版本的没有这个SciTE编辑器（可以网上下载）。
安装过程倒是很简单，直接安装在C盘的根目录下即可（C:\Ruby），下面的3个选项选中，一路【Next】安装成功。
进入CMD命令提示行，来对Rubygems进行升级，并安装watir，他们都是通过网络安装的，执行前最好把本地的防火墙关掉。
具体的安装可以参考：http://watir.com/installation/
gem update –system（如果网络安装rubygems失败，可以尝试http://rubyforge.org/frs/?group_id=126下载最新版，线下安装）
gem install watir[版本号] #不写版本号则取最新版本

然后再安装gem install watir-webdriver
验证ruby是否成功：
C:\Ruby>irb irb(main):001:0> puts "my ruby1.9.3" my ruby1.9.3 => nil irb(main):002:0> puts 6/3

=> nil
irb(main):002:0>
在Ruby186版本中，是自带这个编辑器的，最新版的Ruby没有这个编辑器，我们可以手动去下载安装。
说到ruby+watir自动化测试用的编辑器，主要有一下几个：rubymine（开发专用）、SciTE、NETBeans（有支持ruby版本的）、Eclipse（要安装插件 Ruby Development Tools）。
Ruby编辑器scite下载地址：http://download.csdn.net/detail/wy3552128/4797736
由于当时安装的是最新版本rubyinstaller-1.9.3-p327.exe，安装后，可能会提示：“ruby Watir::IE (NameError)”的错误，也不知道为什么，最后降低了watir、commonwatir、watir-classic、win32-process的版本就可以啦。具体的请查看我的下一遍博文：
gem uninstall watir -v 4.0.2 gem install watir -v 3.0.0 gem uninstall watir-classic -v 3.3.0 gem install watir-classic -v 3.0.0 gem uninstall win32-process -v 0.7.0 gem install win32-process -v 0.6.6
