今天在安装python的goose-extractor开发包时出现如下错误：
D:\Program Files (x86)\Python35-32\Scripts>pip install goose-extractor

Complete output from command python setup.py egg_info:
Traceback (most recent call last):

Command "python setup.py egg_info" failed with error code 1 in C:\Users\ADMINI~1

--------------------------------------------------------------------------------------------------------------------------------
错误原因：
1、我安装的python版本是python-3.5.1-x86.exe
2、goose-extractor-1.0.25依赖BeautifulSoup-3.2.1
3、 BeautifulSoup-3.2.1是用python2.X.X开发的
4、听说python3.X.X系列和python2.X.X系列不兼容？我刚用python，对此还不甚了解，现在发现print不兼容。。。
-------------------------------------------------------------------------------------------------------------------------------------------------------------
解决方法：
1、安装python的版本选择python-2.7.11版本即可。
