运行Python自动化脚本遇TypeError：WebDriver不支持executable_path参数

错误原因 #

Selenium 4.x及以上版本移除了webdriver.Chrome()的executable_path参数，改用Service类管理驱动程序路径，传入该参数会触发类型错误。

修复步骤 #

1. 导入Service类
   在脚本开头添加导入语句：

from selenium.webdriver.chrome.service import Service

2. 修改驱动初始化代码
   将原代码中初始化Chrome驱动的行：

bot = webdriver.Chrome(options=options, executable_path=CM().install())

替换为：

service = Service(executable_path=CM().install())
bot = webdriver.Chrome(service=service, options=options)

额外优化（可选） #

Selenium 4.x已弃用find_element_by_xpath、find_elements_by_xpath这类旧方法，建议改用新API，需先导入By类：

from selenium.webdriver.common.by import By

然后替换代码中的查找元素方法，例如：

• bot.find_element_by_xpath(xpath) → bot.find_element(By.XPATH, xpath)
• bot.find_elements_by_xpath(xpath) → bot.find_elements(By.XPATH, xpath)

修改后的完整脚本 #
