selenium-webdriver - 使用 Python 执行 Chrome 在 Selenium 中无头，但抛出错误

问题描述

根据这里的答案，我试图让 Chrome 在我的脚本中无头运行。

下面的代码片段在一个名为的函数内，该函数login()登录到我们的ERP 系统：

if headless == True:
    options = Options()
    options.headless = True
    #Load webdriver
    driver = webdriver.Chrome(options=options, executable_path=r'C:/Users/d.kelly/Desktop/Python/chromedriver_win32/chromedriver.exe')
if headless == False:
    driver = webdriver.Chrome('C:/Users/d.kelly/Desktop/Python/chromedriver_win32/chromedriver.exe')
window_before_login = driver.window_handles[0]
### Removed Code Block that fills out login form and clicks 'Login' button ###
# Switch to new window ERP (PLEX)  launches and close original blank one no longer needed.
window_before_login = driver.window_handles[0]
window_title = driver.title
driver.switch_to.window(window_before_login)
driver.close()
driver.switch_to.window(driver.window_handles[0])

当我这样调用我的函数时：

login(headless=False)

它不会引发任何错误，并且我的整个脚本执行得很好。

当我这样调用我的函数时：

def login(headless=True)

我收到以下错误：

我正在使用Chrome Version 79.0.3945.130 (Official Build) (64-bit),Selenium 3.141.0和Python 3.7.4.

任何想法我做错了什么？谢谢！
