我在python3.4下装好selenium3.0, 运行以下代码测试
from selenium import webdriver
driver = webdriver.Firefox()
driver.get('http://www.baidu.com')
结果报错如下：
>>>
Traceback (most recent call last):
File "F:\爬虫\esuppliersindia\test.py", line 1, in <module>
from selenium import webdriver
File "C:\Python34\lib\site-packages\selenium-3.0.0b2-py3.4.egg\selenium\webdriver\__init__.py", line 25, in <module>
from .safari.webdriver import WebDriver as Safari # noqa

executable_path = os.environ.get("SELENIUM_SERVER_JAR")
^
TabError: inconsistent use of tabs and spaces in indentation
>>>
我查了...\safari\webdriver.py文件,看到这样的代码
if not executable_path is None:
executable_path = os.environ.get("SELENIUM_SERVER_JAR")
self.service = Service(executable_path, port=port, quiet=quiet,use_legacy=use_legacy_driver)
self.service.start()
联想到py3要求tab和space不能混用，于是我吧 executable_path之前的空格删掉，再打8个空格，这样又报错：
executable_path = os.environ.get("SELENIUM_SERVER_JAR")
^
IndentationError: expected an indented block
于是我把 if not executable_path is None: 下的3句缩进，就是这样，
if not executable_path is None:
executable_path = os.environ.get("SELENIUM_SERVER_JAR")
self.service = Service(executable_path, port=port, quiet=quiet, use_legacy=use_legacy_driver)
self.service.start()
这下问题更大了，报错如下：
>>>

这下我是真没辙了，各位大神有没有遇到同样的问题呢？请教。

是不是少了，#coding:utf-8

楼主如何解决的

我的也是这样

缩进三行的做法是对的，这里也有人提：
http://stackoverflow.com/questions/38917412/python3-5-2-selenium-3-0-0b2-firefox-48-0-inconsistent-use-of-tabs-and-spaces
这个是其他的问题，我用MAC也出现了，现在的问题主要是看geckodriver这个有没有装，然后装了的话有没有放在PATH里

geckodriver,火狐浏览器更新后selenium3.0 更新，我去年写的爬虫都不能用了，发现需要下geckodriver,

这个问题有谁知道解决办法？？
