终于解决了我的问题。

1. 将Selenium 3.14安装/升级到Selenium 4.0.0a5

2. 将Python代码更改为以下内容：

   using edge directly, since you can see ‘selenium.webdriver.chromium.webdriver’ used in site-packagesseleniumwebdriveredgewebdriver.py

   from selenium import webdriver
   from selenium.webdriver.edge.options import Options
   from selenium.webdriver.edge.service import Service
   from selenium.webdriver.edge.webdriver import WebDriver
   …
   …
   driveroptions = Options()
   

   remember to set use_chromium

   driveroptions.use_chromium = True
   driveroptions.add_argument(‘–start-maximized’)
   driveroptions.binary_location = env_programfiles_x86 + “MicrosoftEdgeApplicationmsedge.exe”

   service = Service(executable_path=”msedgedriver.exe”)
   driver = webdriver.Edge(options=driveroptions, service=service)

   driver.set_page_load_timeout(40)
   driver.get(page_url)
