在運(yùn)行django程序的時(shí)候，出現(xiàn)下面的問(wèn)題

RuntimeError: maximum recursion depth exceeded in cmp

說(shuō)是遞歸深度有問(wèn)題，在網(wǎng)上查了好久，終于解決了。

原來(lái)是python自己的問(wèn)題，需要將fuctools.py進(jìn)行修改。具體如下

To fix the PRoblem replace this (about line 56 in python/Lib/fuctools.py):

    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)]}
to that:
    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)]}
