python2.7+selenium3.5搭建环境时报错

Senya翩鸿

求助！在MAC上安装了pycharm，也安装了selenium3.5 在执行
from selenium import webdriver
import time
dr = webdriver.Firefox()
dr.get('http://baidu.com')
time.sleep(5)
print 'Broswer will be closed'
dr.quit()
print 'Broswer is close'
这段代码的时候，连续碰雷

下载火狐驱动了吗，下了的话没把驱动加到环境变量里吧，需要制定路径
