Chrome127适配Chromedriver失败，Selenium报错及PATH配置问题求助

问题核心 #

Chrome版本127.0.6533.89，已下载对应127.0.6533.88版本的chromedriver并加入系统PATH，但运行Python代码时仍触发以下异常：

• Selenium Manager反复尝试旧版本chromedriver（126至122），无法识别已下载的127版本
• 提示'chromedriver.exe' executable needs to be in PATH

解决方案 #

1. 禁用Selenium Manager自动驱动查找 #

Selenium 4.x默认启用Selenium Manager自动管理驱动，可能会忽略手动指定的路径。在ChromeOptions中添加参数禁用该功能：

chrome_options.add_argument("--disable-selenium-manager")

修改后的get_webpage函数片段：

def get_webpage():
    chrome_options = Options()
    chrome_options.add_argument("--no-sandbox")
    chrome_options.add_argument("--disable-gpu")
    chrome_options.add_argument('--disable-dev-shm-usage')
    # 禁用Selenium Manager，强制使用手动指定的驱动
    chrome_options.add_argument("--disable-selenium-manager")

    chromedriver_path = 'C:/Users/Kovy/Download/chromedriver-win64/chromedriver-win64/chromedriver.exe'
    service = Service(executable_path=chromedriver_path)

    driver = webdriver.Chrome(service=service, options=chrome_options)
    # 后续代码保持不变

2. 验证chromedriver路径正确性 #

• 检查路径是否存在拼写错误（例如Download是否应为Downloads）
• 建议将chromedriver.exe移动到更简洁的路径（如C:/chromedriver.exe），避免嵌套过深导致识别问题

3. 确认PATH配置生效 #

• 重启Python IDE或终端，确保PATH修改生效
• 在命令行执行chromedriver --version，若返回版本信息则PATH配置正确；若报错，重新检查添加的目录是否正确

4. 验证驱动版本兼容性 #

Chrome 127.0.6533.89与chromedriver 127.0.6533.88通常兼容，若仍有问题：

• 重新下载chromedriver，确保文件未损坏
• 若有条件，下载与Chrome完全一致版本号的chromedriver
