尝试启动 Firefox 时出现 Python selenium 错误 [英] Python selenium error when trying to launch firefox

问题描述

尝试在 ipython notebook 中使用 Selenium 打开 Firefox 时出现错误.我环顾四周，发现了类似的错误，但没有与我得到的错误完全匹配.任何人都知道问题可能是什么以及我如何解决它?我使用的是 Firefox 22.

我输入的代码如下:

from selenium import webdriver驱动程序 = webdriver.Firefox()

代码返回的错误如下:

解决方案

尝试在初始化时指定您的 Firefox 二进制文件 Firefox()

from selenium import webdriver从 selenium.webdriver.firefox.firefox_binary 导入 FirefoxBinarybinary = FirefoxBinary('path/to/binary')驱动程序 = webdriver.Firefox(firefox_binary=binary)

FirefoxDriver 寻找的默认路径位于 %PROGRAMFILES%Mozilla Firefoxfirefox.exe.请参阅 FirefoxDriver

或者将 Firefox 二进制文件的路径添加到 Windows 的 PATH.>

I am getting an error when trying to open Firefox using Selenium in ipython notebook. I've looked around and have found similar errors but nothing that exactly matches the error I'm getting. Anybody know what the problem might be and how I fix it? I'm using Firefox 22.

The code I typed in was as follows:

from selenium import webdriver
driver = webdriver.Firefox()

The error the code returns is as follows:

    WindowsError                              Traceback (most recent call last)

解决方案

Try specify your Firefox binary when initialize Firefox()

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary('path/to/binary')
driver = webdriver.Firefox(firefox_binary=binary)

The default path FirefoxDriver looking for is at %PROGRAMFILES%Mozilla Firefoxfirefox.exe. See FirefoxDriver

Or add your path of Firefox binary to Windows' PATH.
