python 用selenium写爬虫打开火狐

Question

import os
from selenium import webdriver

browser = webdriver.Firefox()
print driver.get('http://v.qq.com/x/cover/d4rkjpicdk01ybo.html')

这么写为什么会报错？

Traceback (most recent call last):
File "C:\Users\JAY\Desktop\2.py", line 4, in
browser = webdriver.Firefox()
File "C:\Python27\lib\site-packages\selenium-3.0.0b2-py2.7.egg\selenium\webdriver\firefox\webdriver.py", line 65, in init
self.service.start()
File "C:\Python27\lib\site-packages\selenium-3.0.0b2-py2.7.egg\selenium\webdriver\common\service.py", line 71, in start
os.path.basename(self.path), self.start_error_message)
WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
这错误是什么意思？

你好，需要安装火狐驱动，然后配置到环境变量中。当然也可以把驱动放到system32中，希望对你有用
