使用Selenium操作Microsoft Edge时遭遇NoSuchDriverException错误求助

执行webdriver.Edge()时出现以下错误，核心原因是Selenium Manager无法解析EdgeDriver下载服务器的DNS，导致无法自动获取驱动：

最终触发上层异常：

解决方法 #

1. 手动下载并配置EdgeDriver #

• 步骤1：确认Edge版本：打开Edge浏览器，进入「设置和更多」→「设置」→「关于Microsoft Edge」，查看浏览器的版本号（例如119.0.2151.58）。
• 步骤2：下载对应版本的EdgeDriver：前往微软官方EdgeDriver下载页面，选择与浏览器版本完全匹配、对应系统（Windows 64位）的驱动包，下载后解压得到msedgedriver.exe。
• 步骤3：配置驱动路径：
  • 方法一：将msedgedriver.exe移动到Python安装目录的Scripts文件夹下（例如C:\Python311\Scripts），或添加到系统环境变量PATH中。
  • 方法二：在代码中直接指定驱动路径：

    from selenium import webdriver
    from selenium.webdriver.edge.service import Service
    
    # 替换为你的msedgedriver.exe实际路径
    driver_path = r"C:\Users\Queensley\Desktop\msedgedriver.exe"
    service = Service(driver_path)
    browser = webdriver.Edge(service=service)
    

2. 排查网络问题 #

• 检查网络是否能正常访问EdgeDriver的下载服务器，若处于受限制的网络环境（如公司内网），尝试切换网络（比如使用手机热点）。
• 若使用代理，需在代码中配置代理参数，确保Selenium Manager能正常连接服务器。
