WebDriverException:消息:通过Python 3.7使用GeckoDriver Firefox v65和Selenium的newSession [英] WebDriverException: Message: newSession with GeckoDriver Firefox v65 and Selenium through Python 3.7

问题描述

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:

I am trying to use Python 3.7 + Selenium + Geckodriver + Firefox v65.0 for scrapping. New window is opening, but Firefox does not sent correct respond about session to Python and crashes after 30 seconds with an error:

WebDriverException: Message: newSession

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

In case if I downgrade Firefox to version 60.0.2 - all works correctly with all versions Geckodriver v0.22, 0.23 and 0.24.

即使我尝试使用从0.22到0.24的其他geckodrivers，Firefox 63.0、65.0和66beta版本也不起作用.

Firefox version 63.0, 65.0 and 66beta does not work, even if I try different geckodrivers from 0.22 to 0.24.

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

System: Windowns 7 x64+ Firefox 65.0 64bit, newest selenium, 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")

问题: 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?

Queston: How it is possible to make Firefox 65 work with Selenium? Maybe in newer versions of Firefox (61.0+) I should specify some options during connection?

推荐答案

不确定哪里出了问题，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:

Not sure where things are going wrong but there seems to be a mixup with multiple binary versions. However I am using the following configuration:

• Python:3.6.1

• 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.

我已经采用了自己的代码，并添加了自变量 executable_path 来执行它，如下所示:

I have taken your own code and executed it adding the argument executable_path as follows:

• 代码块:

• Code Block:

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:

Console Output:

Page Title is : Google
