在使用selenium启动谷歌Chrome浏览器的时候，是需要用到chromedirver的，两者之间的版本是需要匹配的，否则会出现下面类似的报错：

导致原因是因为本机电脑的Chrome浏览器的版本和chromedirver驱动的版本不一致
解决办法
到谷歌驱动仓库里下载对应版本的驱动
下载地址 http://chromedriver.storage.googleapis.com/index.html
编辑
打开Chrome浏览器-》设置-》关于Chrome 或者帮助-》关于 Google Chrome 里查看 浏览器版本
编辑
以上图为例查询 驱动仓库里，89.开头的chromedriver驱动即可
编辑
没有行windows x64位的驱动，下载win32即可通用。
