mac配置python+selenium时遇到的相关问题

1.安装好pip+selenium+python之后

运行以下代码验证是否环境配置成功

from selenium import webdriver
import time
dr = webdriver.Firefox()
time.sleep(5)
print 'Browser will be closed'
dr.quit()
print 'Browser is close'

发现一个问题，报错

/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /Users/rita/PycharmProjects/one/selenium/test1.py
Traceback (most recent call last):
File "/Users/rita/PycharmProjects/one/selenium/test1.py", line 3, in <module>
dr = webdriver.Firefox()
File "/Library/Python/2.7/site-packages/selenium-3.3.1-py2.7.egg/selenium/webdriver/firefox/webdriver.py", line 145, in __init__

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

解决方案：

发现是firefox版本过高，不能用默认路径，需要提供的geckodriver完整路径，我重新下载了一个，下载地址：https://github.com/mozilla/geckodriver/releases 

方法<一>:

下载完成之后在代码中录入geckodriver的绝对路径，代码如下：

from selenium import webdriver
import time
dr = webdriver.Firefox(executable_path= '/Users/rita/Downloads/geckodriver')
time.sleep(5)
print 'Browser will be closed'
dr.quit()
print 'Browser is close'

编译执行能够看到firefox浏览器启动，完成之后输出如下：代表环境配置成功

/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /Users/rita/PycharmProjects/one/selenium/test1.py
Browser will be closed
Browser is close

Process finished with exit code 0

方法<二>：

geckodriver放到/usr/local/bin下即可，运行程序中不加绝对路径也能运行成功

运行以下代码成功

from selenium import webdrive
4000
r
import time
dr = webdriver.Firefox()
time.sleep(5)
print 'Browser will be closed'
dr.quit()
print 'Browser is close'
