Question

我正在尝试运行以下Python代码，通过Selenium创建一个Firefox Webdriver窗口：

from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://www.google.com")

虽然这段代码几周前工作正常，但它现在会产生以下预感信息：

 Traceback (most recent call last):
  File "test.py", line 2, in <module>
    driver = webdriver.Firefox()
  File "c:\python27\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 60, in __init__
    self.binary, timeout),

有谁知道这意味着什么，或者我可以采取哪些措施来纠正错误并让代码按预期运行？我通过Google搜索找到了相关的错误消息，但没有任何可以让我解决问题。

对于它的价值，我可以通过将上面的第二行更改为driver = webdriver.Chrome()来打开Chrome Webdriver而不会出现问题。

我正在使用Python 2.7，Selenium 2.35.0（我刚刚在Windows 8计算机上运行“pip install selenium --upgrade”和Firefox 26.0。非常感谢其他人提供的任何提示或建议。

Answer 1

Selenium 2.35与Firefox 26不兼容。正如release notes所述，在Selenium 2.39中添加了FF 26支持。您需要更新到2.39。请改为pip install -U selenium。

Answer 2

不确定它在Windows上是否也能正常工作，但对我来说，Firefox 26和selenium 2.37.0的组合工作正常。

Answer 3

我在Win8.1 FF28和python3.4 / selenium 2.41中也有这个问题。但是在我将FF降级到24之后，它起作用了！我也在Win8.1 / FF27 / Python3.4 / Selenium 2.41中进行了测试，它也有效。

Answer 4

我刚刚遇到FF36和selenium 2.44.0。重新安装FF 32.0修复它。

Answer 5

我在Kubuntu 14.04桌面上遇到了同样的问题，我删除了Firefox 47.XX并重新安装了Firefox 45.XX并解决了问题。

下载firefox debian软件包

apt-get purge firefox
dpkg -i firefox-XXXXXXXXXX.deb

Python：Selenium Firefox Webdriver失败并显示错误：'无法加载配置文件... WARN addons.xpi ...“
