Question

当我从用户jenkins（Linux Mint）运行此脚本时，我收到此错误，并且当从我的用户运行它时，它可以工作。 Jenkins用户是使用jenkins服务创建的。我已经安装了virtualenv。

import unittest

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait

DRIVER = None

def getOrCreateWebdriver():
    global DRIVER
    DRIVER = DRIVER or webdriver.Firefox()
    return DRIVER


class LoginTest(unittest.TestCase):
    def setUp(self):
        self.browser = getOrCreateWebdriver()

    def test_Loggin(self):pass
         browser = self.browser

    def tearDown(self):
        self.browser.close()

if __name__ == '__main__':
    unittest.main(verbosity=2)

From user jenkins when i run this script i get error :
test_Loggin (__main__.LoginTest) ... ERROR
/usr/lib/python3.4/unittest/case.py:602: ResourceWarning: unclosed file <_io.BufferedWriter name='/dev/null'>
  outcome.errors.clear()

当您以自己的身份登录时，您需要执行echo $DISPLAY并记下它打印的显示信息。随后当您以jenkins服务身份登录时，您需要xhost +，DISPLAY=[display-info]; export DISPLAY。（display-info是你从echo $ DISPLAY获得的，忽略方括号，它们不应该在命令中指定）

希望这应该有效。我没有类似的环境可以测试，只是提到我记得已经做了很久的事情。

来自一个用户的Python 3运行脚本可以正常工作，但另一个用户不运行？
