我的系统是win10，python是用Anacoda安装的，通过pip安装了selenium 后使用Chromedriver发现报错，pip安装selenium如下：
|
1
|
pip install selenium |
报错具体如下：
driver=webdriver.Chrome()
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

selenium操作chrome浏览器需要有ChromeDriver驱动来协助。
什么是ChromeDriver？
ChromeDriver是Chromium team开发维护的，它是实现WebDriver有线协议的一个单独的服务。ChromeDriver通过chrome的自动代理框架控制浏览器，ChromeDriver只与12.0.712.0以上版本的chrome浏览器兼容。
解决办法：
1.下载Chromedriver，网盘：https://pan.baidu.com/s/1c3KLRJa
2.把Chromedriver解压到D:\app\Anaconda\Scripts\下，重新运行命令即可打开Chromedriver
在运行了
driver=webdriver.Chrome()
driver.get('www.baidu.com')
之后出现报错：
>>> driver.get('m.weibo.com')

原因是打开的域名一定要加前http://，改正后如下：
