python - selenium.common.exceptions.WebDriverException : Message: connection refused

Question

这是我的代码:

from selenium import webdriver

browser = webdriver.Firefox()

browser.get('http://www.python.org')

browser.close()

当我运行这个脚本时它启动了 firefox 浏览器，但是页面是空白的，然后命令行显示错误消息:

Traceback (most recent call last):
  File "ad.py", line 3, in <module>
    browser = webdriver.Firefox()
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 76, in __init__
    keep_alive=True)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 92, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 179, in start_session
    response = self.execute(Command.NEW_SESSION, capabilities)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 236, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 192, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: connection refused

我的python版本是2.7.3，selenium版本是selenium-3.0.0.b3.egg-info

请问我该如何解决这个问题...

检查你的geckodriver.log文件(应该和python文件在同一个目录)

如果它说Error: GDK_BACKEND does not match available displays 然后安装 pyvirtualdisplay:

pip install pyvirtualdisplay selenium

您可能还需要 xvfb:

sudo apt-get install xvfb # Debian

sudo yum install Xvfb # Fedora

然后尝试添加这段代码:

from pyvirtualdisplay import Display
display = Display(visible=0, size=(800, 600))
display.start()

完整示例:

from pyvirtualdisplay import Display
from selenium import webdriver

display = Display(visible=0, size=(800, 600))
display.start()

browser = webdriver.Firefox()
browser.get('http://www.python.org')

browser.close()
