我正在尝试在我的 Mac 上安装 Django。当我运行命令 python manage.py runserver 时。我收到错误 RuntimeError: maximum recursion depth exceeded in cmp.我在下面粘贴了我的错误消息。我什至将 setrecursion 限制增加到 2000 并尝试过,它没有用。感谢您帮助解决此问题...

最佳答案
问题出在 functools.py 文件中。这个文件来自 Python。我刚刚安装了一个新版本的 python 2.7.5 并且文件是错误的(我有另一个较旧的 python 2.7.5 安装并且文件 functools.py 是正确的)
要解决此问题,请替换此(关于 python\Lib\fuctools.py 中的第 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)]
}
对此:
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)]
}
