print('Need your login credential')

输出:

知道出了什么问题吗？我尝试过谷歌但没有成功。

请您参考如下方法:

如果您在没有显示屏的系统上运行 Firefox，请确保使用 headless 模式。

from selenium import webdriver 
from selenium.webdriver.firefox.options import Options 
 
options = Options() 
options.headless = True 
driver = webdriver.Firefox(options=options) 

此外，请确保您拥有 Firefox、Selenium 和 Geckodriver 的兼容版本: https://firefox-source-docs.mozilla.org/testing/geckodriver/Support.html
