Selenium - 不支持在常规用户 session 中以 root 身份运行 Firefox

Question

我对 Selenium 非常陌生，突然间无缘无故地出现一个错误阻止我运行任何 Selenium 测试。

这是我运行 Python 脚本时遇到的错误:

2018-05-14 12:07:52,766 [INFO ]  Getting Selenium setup here.
Traceback (most recent call last):
  File "test.py", line 308, in <module>
    webcrawler.crawl()
  File "test.py", line 177, in crawl
    self.web_crawl.setup()
  File "/test/src/webcrawlers/utils/webcrawl_lib.py", line 83, in setup
    self.browser = webdriver.Firefox(firefox_profile=profile)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 162, in __init__
    keep_alive=True)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 154, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 243, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 312, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 1

现在我通常可以调试这些问题。然而，geckodriver.log 并没有给我太多的帮助:

1526299672891   geckodriver     INFO    geckodriver 0.20.1
1526299672895   geckodriver     INFO    Listening on 127.0.0.1:48641
1526299673899   mozrunner::runner       INFO    Running command: "/usr/bin/firefox" "-marionette" "-profile" "/tmp/rust_mozprofile.YNIc2l05QiIr"
Running Firefox as root in a regular user's session is not supported.  ($HOME is /home/test which is owned by test.)

环境:

• Geckodriver:0.20.1
• Selenium :3.12.0
Python:2.7。我也尝试过使用 3
• 火狐:60.0

我什至尝试改用 Chrome，但设置会挂起并给出一个独特的错误。

附注是，这是在 Amazon AWS 上，我不是该帐户的管理员。也许这方面发生了一些变化。

我在 geckodriver 0.21.1、Selenium 3.12.0 和 Python 3.5.2 上也遇到了同样的问题。它对我在 Ubuntu 17.04 上使用 sudo apt-get purge firefox, firefox-dev 删除 Firefox 和 (firefox-dev) 有用，然后我手动安装 Firefox 版本 50.0 :

wget http://ftp.mozilla.org/pub/firefox/releases/50.0/linux-$(uname -m)/en-US/firefox-50.0.tar.bz2
tar -xjf firefox-50.0.tar.bz2
sudo mv firefox /opt/
sudo mv /usr/bin/firefox /usr/bin/firefox_old
sudo ln -s /opt/firefox/firefox /usr/bin/firefox

完成这些步骤后，它也可以在 root 下使用。
