我想使用 Selenium 的 Firefox 驱动程序。但我得到了如下所示的错误。火狐可能没有正确安装吗？

------ 我的来源 ------

from selenium import webdriver

driver = webdriver.Firefox()

------ 我的源码完------

这是返回的错误：

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    browser = webdriver.Firefox()
  File "/usr/local/lib/python2.7/site-packages/selenium-2.25.0-py2.7.egg/selenium/webdriver/firefox/webdriver.py", line 51, in __init__

I faced the same error but got fixed when I installed firefox. Didn't realise that firefox was not installed. Check it out.

selenium webdriver 为您提供对 Web 内容的编程访问。它驱动一个真正的浏览器，所以是的，你需要安装 Firefox 来实例化webdriver.Firefox().
