1. 保证ruby和gem没有问题的前提下

   rubyinstaller-1.9.2-p180.exe  以管理员打开安装 安装时 两个单选框 都选中
   

   C:\Documents and Settings\Administrator>ruby
   ruby 1.9.2p180 (2011-02-18) [i386-mingw32]ruby -v

   更新rubygem  gem update --system
   

   C:\Documents and Settings\Administrator>gem -v
   1.5.2

   
   

   gem install/list/uninstall selenium-webdriver
