今天想用Python实现一个自动刷新网页的脚本，需要用到selenium。
因为刚开始没有指定chromedriver，所以报错：
Traceback (most recent call last):
File "D:\Anaconda3\lib\site-packages\selenium\webdriver\common
\service.py", line 76, in start

startupinfo)
FileNotFoundError: [WinError 2] 系统找不到指定的文件。
During handling of the above exception, another exception occurred:

executable needs to be in PATH. Please see
https://sites.google.com/a/chromium.org/chromedriver/home然后我去下载chromedriver，随便下了一个版本的，结果又报错：

return self._sock.recv_into(b)
ConnectionResetError: [WinError 10054] 远程主机强迫关闭了一个现有的连接。之后继续百度寻找答案，才发现：
再使用selenium打开chrome浏览器的时候，需要用chromedriver，而chromedriver与
chrome的版本也是要相互适宜的，对应关系如下：
|chromedriver版本|支持的Chrome版本
| - | :-: |
|v2.36 |v64-66
|v2.35 |v62-64
|v2.34 |v61-63
|v2.33 |v60-62
|v2.32 |v59-61
|v2.31 |v58-60
|v2.30 |v58-60
|v2.29 |v56-58
所以，先在浏览器地址栏输入：chrome://version
得到浏览器的版本，之后找到对应的chromedriver版本，并下载。
