selenium.common.exceptions.WebDriverException: Message: newSession
参考链接：https://blog.csdn.net/qq_29012939/article/details/86591383
解决方法：
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
去掉browser.close()即可
