Python selenium error when trying to launch firefox
提问by CultureQuant
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.

Try specify your Firefox binary when initialize Firefox()
初始化时尝试指定您的 Firefox 二进制文件 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 Firefox\firefox.exe. See FirefoxDriver
FirefoxDriver 寻找的默认路径在%PROGRAMFILES%\Mozilla Firefox\firefox.exe。请参阅Firefox 驱动程序
Or add your path of Firefox binary to Windows' PATH.
或者将 Firefox 二进制文件的路径添加到 Windows 的PATH。

I got the same error when I set environment variable export PYTHONDONTWRITEBYTECODE=1to get rid of pyc files on every test run. I was able to revert the change by updating selenium pip install --upgrade selenium. OSX (10.10)
当我设置环境变量export PYTHONDONTWRITEBYTECODE=1以在每次测试运行时删除 pyc 文件时，我遇到了同样的错误。我能够通过更新 selenium 来恢复更改pip install --upgrade selenium。OSX (10.10)
