WebDriverException：消息：通过Python 3.7使用GeckoDriver Firefoxv65和Selenium的newSession

Question

我正在尝试使用Python 3.7 + Selenium + Geckodriver + Firefox
v65.0进行剪贴。新窗口打开，但是Firefox没有向Python发送有关会话的正确响应，并在30秒后崩溃并显示错误：

WebDriverException: Message: newSession

如果我将Firefox降级到60.0.2版，则所有版本的Geckodriver v0.22、0.23和0.24均可正常使用。

Firefox 63.0、65.0和66beta版本不起作用，即使我尝试使用从0.22到0.24的其他geckodrivers也是如此。

系统 ：Windowns 7 x64 + Firefox 65.0 64位，最新的硒，geckodriver v0.24.0。

我的代码：

from selenium import webdriver 
from selenium.common.exceptions import NoSuchElementException

with webdriver.Firefox() as driver:
    driver.get("http://google.com")

错误说明：

Queston： 如何使Firefox 65与Selenium兼容？也许在较新版本的Firefox（61.0+）中，我应该在连接期间指定一些选项吗？

Answer 1

不知道哪里出了问题，但似乎有多个二进制版本的混淆。但是我正在使用以下配置：

• 的Python：3.6.1

  C:\Users\user_name>python
  

  Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 17:54:52) [MSC v.1900 32 bit (Intel)] on win32
  Type “help”, “copyright”, “credits” or “license” for more information.
  

• 硒：3.141.0

  C:\Users\user_name>pip show -V selenium
  

  Name: selenium
  Version: 3.141.0
  Summary: Python bindings for Selenium
  Home-page: https://github.com/SeleniumHQ/selenium/
  Author: UNKNOWN

  Location: c:\python\lib\site-packages
  Requires: urllib3
  Required-by:
  

• 壁虎驱动程序：0.24.0

  C:\Utility\BrowserDrivers>geckodriver.exe -V
  

  geckodriver 0.24.0 ( 2019-01-28)

• Firefox：Mozilla Firefox 65.0

  C:\Program Files\Mozilla Firefox>firefox -v |more
  

  Mozilla Firefox 65.0

我已经采用了自己的代码并执行了添加 参数 的代码， executable_path 如下所示：

• 代码块：

  from selenium import webdriver
  

  with webdriver.Firefox(executable_path=r’C:\Utility\BrowserDrivers\geckodriver.exe’) as driver:
  driver.get("http://google.com”)
  print(“Page Title is : %s” %driver.title)
  driver.quit()

• 控制台输出：

  Page Title is : Google
