求助：Selenium Manager无法自动下载ChromeDriver，求自动解决方案

问题描述 #

我正在学习Selenium，但基础脚本无法运行。Chrome版本为117.0.5938.150，按说Chrome 114+版本Selenium会自动匹配下载对应ChromeDriver，但这个功能失效了，不想手动下载，求自动解决方法。

测试代码 #

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://www.selenium.dev/selenium/web/web-form.html")

driver.quit()

报错信息 #

The above exception was the direct cause of the following exception:

自动解决方法 #

从报错信息看，核心问题是Selenium Manager无法连接谷歌的Driver下载服务器，以下是几个自动解决的方案：

• 配置网络代理：如果你的网络需要代理才能访问外网，在代码开头添加代理环境变量配置：

  import os
  # 替换成你的代理地址和端口
  os.environ['HTTP_PROXY'] = 'http://proxy.example.com:8080'
  os.environ['HTTPS_PROXY'] = 'http://proxy.example.com:8080'
  

• 升级Selenium到最新版：旧版本的Selenium Manager可能存在网络兼容问题，执行命令更新：

  pip install --upgrade selenium
  

• 切换国内镜像源：通过设置环境变量，让Selenium Manager从国内CDN下载ChromeDriver，避免连接谷歌服务器超时。在Windows命令行执行：

  setx SE_MANAGER_GOOGLE_CDN "https://registry.npmmirror.com/-/binary/chromedriver"
  

  执行后重启VSCode再运行脚本即可。

• 检查防火墙/杀毒软件：临时关闭系统防火墙或杀毒软件，确认是否是它们阻断了Selenium Manager的网络请求，后续可将selenium-manager.exe加入白名单。
