WebDriverException：消息：通过 Python 3.7 使用 GeckoDriver Firefox v65 和 Selenium 的 newSession

Question

我正在尝试使用 Python 3.7 + Selenium + Geckodriver + Firefox v65.0 进行抓取。新 window 正在打开，但 Firefox 没有向 Python 发送有关会话的正确响应，并在 30 秒后崩溃并出现错误：

WebDriverException: Message: newSession

如果我将 Firefox 降级到版本 60.0.2 - 所有版本都可以正常工作 Geckodriver v0.22、0.23 和 0.24。

Firefox 版本 63.0、65.0 和 66beta 不起作用，即使我尝试了从 0.22 到 0.24 的不同 geckodriver。

系统：Windowns 7 x64+ Firefox 65.0 64 位，最新的 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")

错误描述：

奎斯顿： 如何让 Firefox 65 与 Selenium 一起工作？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？

Answer 1

不确定哪里出了问题，但似乎混淆了多个二进制版本。但是我使用以下配置：

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

我已经使用了你自己的代码并添加了参数 executable_path 如下执行：

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
```
