Django：python manage.py runserver给出RuntimeError：在cmp中超出最大递归深度

我想在Django项目网站上学习Django的第一个教程。我可能会丢失一些东西很明显，但以下所有的指令后，当我来运行命令Django：python manage.py runserver给出RuntimeError：在cmp中超出最大递归深度

python manage.py runserver

我得到张贴在此请求帮助结束的错误（我已经发布只有前几行为了简洁，错误消息的重复行）。

以下是我在网上找到的一些解决方案/建议，但对我没有帮助。

1）sys.setrecursionlimit（1500）。

这不适合我。 2）。 Django RuntimeError: maximum recursion depth exceeded

这也不是一个选项，因为我没有使用PyDeV，我尝试使用pip卸载和安装Django它没有修复任何东西，我使用的是山狮的原生python，我不打算卸载，因为它不被推荐。 3）。我也试过：

python manage.py runserver --settings=mysite.settings

完全相同的错误作为命令没有的选项设置

任何建议，建议将不胜感激。我正在使用.... Django正式版。 1.5.1我使用PIP和Python 2.7.2安装

    RuntimeError: maximum recursion depth exceeded in cmp

UPDATE：所以我落得这样做是为了做安装VirtualBox的，就可以安装免费的Ubuntu，然后移动到完成的矫枉过正教程...哦，好！

你有上您有任何类oveerridden cmp？ – 2013-04-28 04:53:45

[这是另一个问题，同样的问题。]（http://stackoverflow.com/questions/15236556/django-runtimeerror-maximum-recursion-depth-exceeded） – icktoofay 2013-04-28 04:55:07

@akshar不是我所知的最好的。 – 2013-04-28 06:16:42

问题出在functools.py文件中。这个文件来自Python。我刚安装了一个新版本的python 2.7.5，这个文件是错误的（我有另一个 - python 2.7.5的老版本安装，那里的文件functools.py是正确的）

要解决这个问题，替换这个关于python \ Lib \ fuctools中的第56行。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)] 
}

到：

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)] 
}

只有在互联网上为我工作的解决方案。为什么这不被标记为答案？谢谢，救了我几个小时的挫折。 – 2015-06-26 08:30:45

也适合我！当我更新到Django 1.9时出现了这个错误。谢谢。 – juanifioren 2015-12-11 19:29:08

在更新到Django 1.9之前为我工作。谢谢。 – 2016-03-30 11:31:15

你有可能遇到这样的错误：http://bugs.python.org/issue10042

究竟发生了什么，很难说没有调试，有点我猜的事情，应该是一个字段一个不在这一行：

self.local_fields.insert(bisect(self.local_fields, field), field)

谢谢Lennart对我来说是一个很好的开始。我不知道从哪里开始。 – 2013-04-28 06:17:53

今天我在这里有这个问题。

我们也使用django1.5.1和python2.7.2。

起初，我们安装了django1.4，它工作，但该项目具有django1.5功能，所以它不是一个完整的解决方案。我们安装了python2.7.5，它工作的很好！
