当前临时解决方法 #

手动指定本地ChromeDriver路径：

# path_to_chromedriver = r'C:\Chromedriver\chromedriver.exe'  
# driver = webdriver.Chrome(service=Service(path_to_chromedriver), options=custom_options)

需求 #

无需指定本地ChromeDriver路径，让Selenium自动静默下载匹配的驱动，避免版本不匹配报错。

解决方法 #

1. 清理旧版本ChromeDriver残留 #

• 检查系统PATH环境变量，移除包含旧版本ChromeDriver（v101）的路径，确保Selenium不会优先调用旧驱动。
• 删除Selenium Manager的缓存目录：Windows下路径为%USERPROFILE%\.cache\selenium，删除该目录下的chromedriver相关文件，强制重新下载匹配版本。

2. 修正代码的Options配置 #

代码中同时定义了custom_options和options，但初始化driver时未使用配置好的custom_options，统一配置如下：

options = webdriver.ChromeOptions()
options.add_experimental_option('prefs', {'intl.accept_languages': 'en,en_US'})

service = Service()
driver = webdriver.Chrome(service=service, options=options)

3. 升级Selenium版本 #

Selenium 4.6的Selenium Manager对Chrome 115这类较新版本的支持存在bug，升级到4.10及以上版本可修复更多适配问题，新版本的Selenium Manager能更好地匹配高版本Chrome。

4. 查看Selenium Manager日志排查问题 #

设置环境变量SE_DEBUG=true，运行脚本后查看日志，确认Selenium Manager是否尝试下载驱动、是否存在下载失败或路径识别错误的情况，针对性解决。
