使用Selenium/Python的Firefox驱动程序出错

Question

我在尝试使用Selenium执行一个简单的python脚本时出错。以下是脚本和错误以及我的环境信息（我使用的是虚拟环境）。（当我尝试使用Chrome驱动程序时，我遇到了一个不同的错误）。如有任何帮助，我们将不胜感激。

//脚本//

import mechanize
import urllib2 #requests web pages
from selenium import webdriver
from selenium.common.exceptions import NoSuchAttributeException
from selenium.webdriver.common.keys import Keys #allows us to press keys
import os
import re #regular expressions module
br = mechanize.Browser()
br.set_handle_robots(False)
br.set_handle_refresh(False)
br.addheaders = [('User-agent','Firefox')]
browser = webdriver.Firefox()
browser.get("http://applebees.com")

//错误//

Traceback (most recent call last):

    browser = webdriver.Firefox()

//关于我的环境的信息//

Selenium在默认位置找不到Firefox安装目录/ffirefox可执行文件时会发生此错误。使用默认设置卸载并重新安装firefox，然后再次运行脚本。
