1、我用的浏览器是火狐浏览器，主要原因是geckodriver的版本太低，而浏览器的版本是64.0。

更新为v0.23.0：https://github.com/mozilla/geckodriver/releases

将下载下来的geckodriver.exe放入python安装路径下的Scripts文件夹内

selenium.common.exceptions.InvalidSessionIdException: Message: Tried to run command without establishing a connection

解决方法

1
去掉browser.close()即可
