如果安装的时候出现:

C:\Users\liyingxuan01>gem install watir
ERROR:  Error installing watir:
        The 'ffi' native gem requires installed build tools.

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'


解决方案:

1、下载DevKit

    DevKit-tdm-32-4.5.2-20110712-1620-sfx.exe

 

2、解压DevKit

    解压到C:\DevKit

 

3、安装并测试

     cd到解压目录下:

C:\DevKit>ruby dk.rb init
[INFO] found RubyInstaller v1.9.3 at C:/Ruby193

Initialization complete! Please review and modify the auto-ge
'config.yml' file to ensure it contains the root directories
of the installed Rubies you want enhanced by the DevKit.
