今天使用selenium时遇到如下异常信息：
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

selenium.common.exceptions.WebDriverException: Message: unknown error: Runtime.executionContextCreated has invalid 'context': {"auxData":{"frameId":"1902135EC45F5C7A8A0CD69740B466CA","isDefault":true,"type":"default"},"id":1,"name":"","origin":"://"}
(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与chromedriver版本不一致，解决方案：
异常信息中指出我chrome的版本是70.0.3538.102，而chromedriver版本是2.6.233026，明显版本不对应：
所以就需要去以下网址下载对应版本的chromedriver：
http://npm.taobao.org/mirrors/chromedriver/
找到对应版本的chromedriver下载并放在对应python版本的Scripts文件夹下：
然后就可以正常驱动打开网页了：
如有错误，欢迎指正！
