报错信息：Traceback (most recent call last): File "C:/Users/andy/Desktop/Python_test/baidutest.py", line 4, in <module> driver = webdriver.Firefox() File "C:/Python27/lib/site-packages/selenium/webdriver/firefox/webdriver.py", line 140, in __init__ self.service.start() File "C:/Python27/lib/site-packages/selenium/webdriver/common/service.py", line 81, in start os.path.basename(self.path), self.start_error_message)WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

原因：selenium3.0开始，webdriver/firefox/webdriver.py的__init__中，executable_path=geckodriver。而2.x版本是executable_path=wires。Firefox47版本以上，

解决方式：需要下载第三方插件driver，即geckodriver, 需要在http://docs.seleniumhq.org/download/的 Third Party Drivers, Bindings, and Plugins下面找到Mozilla GeckoDriver。下载并安装，安装完成后添加到Windows的path即可。
