使用 Selenium/Python 的 Firefox 驱动程序出错

Question

我在尝试使用 Selenium 执行简单的 python 脚本时遇到错误。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 驱动程序时出现不同的错误）。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):
  File "scraper_test.py", line 18, in <module>
    browser = webdriver.Firefox()

Answer 1

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。卸载并使用默认设置重新安装 firefox 并再次运行脚本。
