Selenium无法在OpenSUSE 42.1上运行:浏览器似乎已经退出，无法连接 [英] Selenium not working on OpenSUSE 42.1: The browser appears to have exited before we could connect

问题描述

我正在尝试在具有Gnome桌面和Firefox 47的本地计算机上使用Python 3.4运行Selenium.但是，最基本的任务已经失败，即打开浏览器窗口.我知道这个问题已经在几个SO帖子上问过了，但是没有一个答案能解决问题.

I'm trying to run Selenium with Python 3.4 on a local machine with Gnome desktop and Firefox 47. However, the most basic task is already failing, i.e. opening the browser window. I know that this question has been asked on several SO post now, but none of the answers is solving the problem.

我只是用pip install selenium安装了Selenium.当我运行

I simply installed Selenium with pip install selenium. When I run

from selenium import webdriver
driver= webdriver.Firefox()

我得到以下回溯:

WebDriverException                        Traceback (most recent call last)
<ipython-input-2-b517b01341f3> in <module>()

     79 
     80             executor = ExtensionConnection("127.0.0.1", self.profile,
---> 81                                            self.binary, timeout)
     82             RemoteWebDriver.__init__(self,
     83                 command_executor=executor,

     50 
---> 51         self.binary.launch_browser(self.profile, timeout=timeout)
     52         _URL = "http://%s:%d/hub" % (HOST, PORT)
     53         RemoteConnection.__init__(

---> 68         self._wait_until_connectable(timeout=timeout)
     69 
     70     def kill(self):

/usr/lib/python3.4/site-packages/selenium/webdriver/firefox/firefox_binary.py in _wait_until_connectable(self, timeout)
     96             if self.process.poll() is not None:
     97                 # Browser has exited
---> 98                 raise WebDriverException("The browser appears to have exited "
     99                       "before we could connect. If you specified a log_file in "
    100                       "the FirefoxBinary constructor, check it for details.")

WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.

我已经尝试使用pyvirtualdisplay并设置$DISPLAY环境变量，但是没有帮助.

I have already tried using pyvirtualdisplay and setting the $DISPLAY environment variable, but nothing helped.

推荐答案

由于firefox更新到版本47 selenium不再运行.解决方法是使用木偶. Mozilla也建议这么做.

Since firefox update to version 47 selenium is not running any more. A work around is using Marionette. That's also recommended by Mozilla.

您可以使用的替代方法是使用较旧的firefox版本:

An alternative you can use is using older firefox version:

您可以在此处并在此处使用它:

You can download the binary here and use it here:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary('path/to/binary')
driver = webdriver.Firefox(firefox_binary=binary)
