启动django项目报错：RuntimeError: maximum recursion depth exceeded while calling a Python object

启动django项目时报错

C:\Users\jerry.home-pc\PycharmProjects\mysite>python manage.py startapp app01
Traceback (most recent call last):

RuntimeError: maximum recursion depth exceeded while calling a Python object

命令行无法启动，pycharm中也无法启动

分析原因：查看系统python版本号：

C:\Users\jerry.home-pc\PycharmProjects\mysite>python -V
Python 2.7

解决方法：升级python到2.7.5（参考自：https://stackoverflow.com/questions/16369637/maximum-recursion-depth-exceeded-in-cmp-error-while-executing-python-manage-py-r?rq=1）



升级后查看Python版本号：

C:\Users\jerry.home-pc\PycharmProjects\mysite>python -V
Python 2.7.5

升级后启动成功：

C:\Users\jerry.home-pc\PycharmProjects\mysite>python manage.py startapp app01

方法二：修改functools.py文件也能达到同样的效果（未测试，感兴趣的可以自己试试）
