python使用selenium安装chromedriver的问题

环境

win64位，python3.6,

问题与解决

说来也巧，今天无意中解决了两个多月前的问题，即用selenium调用chrome浏览器报错的问题；起因是在知乎中看到了一篇12306抢票的文章，用splinter实现抢票，先把代码贴出来，晚点再研究

好了，言归正传，之前那篇博文贴出了报错，原因不在于防火墙等等，而在于chromedriver版本没有下载对，参考并下载：

http://blog.csdn.net/huilan_same/article/details/51896672，我的chrome浏览器是63的版本，百度了一下，说是要装2.34的版本，参考如下：

简单来说搭建selenium+chrome浏览器的python环境需要如下步骤：

首先已经安装好selenium,然后下载对应版本的chromedriver，然后放到1、\Google\Chrome\Application；2、\Python36\Scripts这两个目录下，再把1的路径添加到环境变量path里，接着测试一下

from selenium import webdriver
driver = webdriver.Chrome()
driver.get("http://www.baidu.com")

可以看到顺利打开了百度页面，测试完毕
