正在使用Python初始化MSEdge浏览器，获取TypeError：Level不是整数或有效字符串：无

问题描述

我正在尝试初始化MSedge浏览器，但遇到错误。

from selenium import webdriver
from selenium.webdriver.edge.service import Service
from webdriver_manager.microsoft import EdgeChromiumDriverManager

s=Service(EdgeChromiumDriverManager().install())
driver = webdriver.Edge(service=s)
driver.get('https://www.google.com')

我使用的是WebDRIVER_MANAGER 3.5.2和Selify 4.0.0请帮帮我 在解决这个问题上。如果你需要任何细节，请告诉我。谢谢 预付

解决方案

这是WebDRIVER_MANAGER 3.5.2的问题。WebDRIVER_MANAGER的记录器有问题。详情请参考this issue和this pull request。

您可以根据拉取请求编辑WebDRIVER_MANAGER的源代码来修复该问题。您可以编辑webdriver_manager/microsoft.py文件，添加import logging并将log_level=None更改为log_level=logging.INFO。然后它就可以与Edge驱动程序很好地配合使用了。
