webDriver的安装

• 查看谷歌浏览器的版本
• 去http://npm.taobao.org/mirrors/chromedriver/下载浏览器版本对应的chromeDriver，notes.txt文件中有写到对应版本，注意查看
• 将下载好的chromeDriver解压好复制到谷歌浏览器安装目录，并未谷歌浏览器添加环境变量
• 打开pycharm 使用pip下载selenium模块
• 创建driver时要制定chromedriver的目录
  

1. <p>driver = webdriver.Chrome(executable_path="C:\Program Files</p><p>(x86)\Google\Chrome\Application\chromedriver.exe")</p>
