windows系統，undetected_chromedriver使用options.add_argument("--headless")

Question

老师好，我在windows环境下使用undetected_chromedriver，旧有的代码运行正常，但只要我加入options.add_argument("–headless")，就会出现错误：

builtins.TypeError: ‘<’ not supported between instances of ‘NoneType’ and 'int’

我查询到相关的错误是说版本的问题，且课程中提到undetected_chromedriver会自动下载chromedriver，这与我windows中的版本(我平常在使用的chrome browser)有甚么关联性吗? 这是甚么样的问题呢，请问该如何解决?

代码:

def build_driver():
     options = ChromeOptions()
     options.add_argument('--disable-blink-features=AutomationControlled')
     options.add_argument('--disable-infobars')
     options.add_argument('--disable-popup-blocking')
     options.add_argument("--headless")
     return uc.Chrome(options)

详细错误：
