python+pycharm+Django报错

报错：

Unhandled exception in thread started by <function wrapper at 0x2d7e410>

Traceback (most recent call last):

File "/root/virtual_dir/wxwebapp_court_nositepkg/lib/python2.7/site-packages/django/utils/autoreload.py", line 226, in wrapper

fn(*args, **kwargs)

.......................省略N多行

File "/usr/local/lib/python2.7/functools.py", line 56, in <lambda>

'__lt__': [('__gt__', lambda self, other: other < self),

.......................省略N多行，重复报上面的错

RuntimeError: maximum recursion depth exceeded in cmp

解决办法：在python目录中的Lib下面找到functools将56行

convert = {

'__lt__': [('__gt__', lambda self, other: other < self),

('__le__', lambda self, other: not other < self),

('__ge__', lambda self, other: not self < other)],

'__le__': [('__ge__', lambda self, other: other <= self),

('__lt__', lambda self, other: not other <= self),

('__gt__', lambda self, other: not self <= other)],

'__gt__': [('__lt__', lambda self, other: other > self),

('__ge__', lambda self, other: not other > self),

('__le__', lambda self, other: not self > other)],

'__ge__': [('__le__', lambda self, other: other >= self),

('__gt__', lambda self, other: not other >= self),

('__lt__', lambda self, other: not self >= other)]

}

修改成：

convert = {

'__lt__': [('__gt__', lambda self, other: not (self < other or self == other)),

('__le__', lambda self, other: self < other or self == other),

('__ge__', lambda self, other: not self < other)],

'__le__': [('__ge__', lambda self, other: not self <= other or self == other),

('__lt__', lambda self, other: self <= other and not self == other),

('__gt__', lambda self, other: not self <= other)],

'__gt__': [('__lt__', lambda self, other: not (self > other or self == other)),

('__ge__', lambda self, other: self > other or self == other),

('__le__', lambda self, other: not self > other)],

'__ge__ ': [('__le__', lambda self, other: (not self >= other) or self == other),

('__gt__', lambda self, other: self >= other and not self == other),

('__lt__', lambda self, other: not self >= other)]

}

解决！
