尝试使用 Selenium 执行简单的 python 脚本时出现错误。这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，我得到一个不同的错误）。任何帮助将不胜感激。

// 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()

当 Selenium 在其默认位置找不到 Firefox 安装目录/firefox 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，然后再次运行该脚本。

一些讨论这个问题的链接：

Selenium：FirefoxProfile 失败，未找到异常

如何用硒处理 OSErrors？
