目的：被测系统要求在 Chrome46 版进行测试。

Chrome 浏览器：
Chrome64（已安装）、Chrome46（绿色版）;
chromedrvier：
64 版-chromedriver(2.35)，46 版-chromedriver(2.21)；
selenium 版本-2.53.6，python 版本-2.7.13

问题阐述

根据最新 chrome 浏览器-chromedriver 映射表，确认客户端已下载对应版本的 chromedriver 文件。分别执行两段代码。其中 “#chrome64 版本代码” 正常启动 64 版 Chrome，而 “#chrome46 版本代码” 启动时会出现浏览器并闪退。

异常如下：
