Question

尝试使用Selenium执行简单的python脚本时出错。以下是脚本和错误以及我的环境信息（我正在使用虚拟环境）。（当我尝试使用Chrome驱动程序时，我收到了不同的错误）。任何帮助将不胜感激。

// SCRIPT //

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//

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，然后再次运行脚本。
