我正在尝试使用Gnome桌面和Firefox 47在本地计算机上使用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。我知道现在已经在几个SO帖子上提出了这个问题,但没有一个答案能解决问题。
我只是使用pip install selenium
安装了Selenium。我跑的时候
from selenium import webdriver
driver= webdriver.Firefox()
我得到以下追溯:
WebDriverException Traceback (most recent call last)
<ipython-input-2-b517b01341f3> in <module>()
----> 1 driver= webdriver.Firefox()
/usr/lib/python3.4/site-packages/selenium/webdriver/firefox/webdriver.py in __init__(self, firefox_profile, firefox_binary, timeout, capabilities, proxy, executable_path, firefox_options)

80 executor = ExtensionConnection("127.0.0.1", self.profile,
---> 81 self.binary, timeout)
82 RemoteWebDriver.__init__(self,
83 command_executor=executor,
/usr/lib/python3.4/site-packages/selenium/webdriver/firefox/extension_connection.py in __init__(self, host, firefox_profile, firefox_binary, timeout)
49 self.profile.add_extension()
50
---> 51 self.binary.launch_browser(self.profile, timeout=timeout)
52 _URL = "http://%s:%d/hub" % (HOST, PORT)
53 RemoteConnection.__init__(
/usr/lib/python3.4/site-packages/selenium/webdriver/firefox/firefox_binary.py in launch_browser(self, profile, timeout)
66
67 self._start_from_profile_path(self.profile.path)
---> 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.
我已尝试使用pyvirtualdisplay
并设置$DISPLAY
环境变量,但没有任何帮助。

由于firefox更新到版本47 selenium不再运行。解决方法是using Marionette。这也是Mozilla推荐的。
您可以使用的另一种方法是使用较旧的firefox版本:
您可以下载二进制here并在此处使用它:
from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
binary = FirefoxBinary('path/to/binary')
driver = webdriver.Firefox(firefox_binary=binary)
