Selenium Firefox Webdriver导致错误：服务geckodriver意外退出。状态码为：2

问题描述

我正在编写一个程序，该程序将在网站中搜索文章内的特定条目，我正在使用针对Python的硒网络驱动程序。

I'm writing a program that will search a website for specific entries inside of articles, I'm using selenium webdriver for Python.

尝试连接到我收到此异常的网站：

While attempting to connect to the site I get this exception:

Traceback (most
recent call last):
  File "search.py", line 26, in <module>
    test.search_for_keywords()
  File "search.py", line 13, in search_for_keywords
    browser = webdriver.Firefox()
  File "C:\Python27\lib\site-packages\selenium-3.0.0b2-py2.7.egg\selenium\webdriver\firefox\webdriver.py", line 65, in __init__
    self.service.start()
  File "C:\Python27\lib\site-packages\selenium-3.0.0b2-py2.7.egg\selenium\webdriver\common\service.py", line 86, in start
    self.assert_process_still_running()
  File "C:\Python27\lib\site-packages\selenium-3.0.0b2-py2.7.egg\selenium\webdriver\common\service.py", line 99, in assert_process_still_running
    % (self.path, return_code)
selenium.common.exceptions.WebDriverException: Message: Service geckodriver unexpectedly exited. Status code was: 2

这是说网络驱动程序意外退出。如何解决此问题？我正在尝试将Firefox版本48.0与python版本2.7.12连接起来

It's saying that the webdriver unexpectedly exited. How can I fix this issue? I'm trying to connect with firefox version 48.0 with python version 2.7.12

推荐答案

最新运行python硒测试Firefox浏览器（以上版本47）

木偶或 Gecko驱动程序是firefox驱动程序的未来版本。 Firefox 47+与Selenium 2.53中使用的驱动程序不兼容，Selenium 3+将使用名为 Marionette或 Gecko Driver（尚未正式发布）的新驱动程序。

"Marionette" or "Gecko Driver" is the future version of firefox driver. Firefox 47+ is not compatible with the driver used in Selenium 2.53, and Selenium 3+ will be using a new driver called "Marionette" or "Gecko Driver" (which isn't officially released yet).

先决条件：

•Mozilla firefox：版本50.0.2（以上版本47）

• Mozilla firefox : Version 50.0.2(Version 47 above)

•Selenium：3.0.2版

• Selenium : Version 3.0.2

•Geckodriver：0.11.1版

• Geckodriver : Version 0.11.1

•Python：版本2.7.3

• Python : Version 2.7.3

设置：

•Selenium： pip install –U硒

• Selenium : pip install –U selenium

•Geckodriver：从，解压缩文件并将其放在文件夹中

• Geckodriver : Download the geckodriver from https://github.com/mozilla/geckodriver/releases , unzip the file and place it in a folder

•使用geckodriver路径设置'Path'环境变量

• Set the ‘Path’ environment variable with geckodriver path

示例脚本：

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

＃提供Firefox二进制路径

binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla Firefox\firefox.exe’)

caps = DesiredCapabilities.FIREFOX.copy()

＃将木偶浏览器设置为True

caps['marionette'] = True

＃启动Firefox实例通过指定geckodriver可执行文件路径

driver = webdriver.Firefox(firefox_binary=binary,capabilities=caps, executable_path`='D:/Installers/geckodriver-v0.11.1-win64/geckodriver')
