今天使用selenium時遇到如下異常信息：
driver.get('https://www.baidu.com')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "D:\python3.7.3-install-path\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 333, in get

(Session info: chrome=70.0.3538.102)
(Driver info: chromedriver=2.6.233026,platform=Windows NT 6.3 x86_64)
其原因就是Chrome與chromedriver版本不一致，解決方案：
異常信息中指出我chrome的版本是70.0.3538.102，而chromedriver版本是2.6.233026，明顯版本不對應：
所以就需要去以下網址下載對應版本的chromedriver：
http://npm.taobao.org/mirrors/chromedriver/
找到對應版本的chromedriver下載並放在對應python版本的Scripts文件夾下：
然后就可以正常驅動打開網頁了：
如有錯誤，歡迎指正！
