Django：python manage.py runserver給出RuntimeError：在cmp中超出最大遞歸深度

我想在Django項目網站上學習Django的第一個教程。我可能會丟失一些東西很明顯，但以下所有的指令後，當我來運行命令Django：python manage.py runserver給出RuntimeError：在cmp中超出最大遞歸深度

python manage.py runserver

我得到張貼在此請求幫助結束的錯誤（我已經發布只有前幾行爲了簡潔，錯誤消息的重複行）。

以下是我在網上找到的一些解決方案/建議，但對我沒有幫助。

1）sys.setrecursionlimit（1500）。

這不適合我。 2）。 Django RuntimeError: maximum recursion depth exceeded

這也不是一個選項，因爲我沒有使用PyDeV，我嘗試使用pip卸載和安裝Django它沒有修復任何東西，我使用的是山獅的原生python，我不打算卸載，因爲它不被推薦。 3）。我也試過：

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

完全相同的錯誤作爲命令沒有的選項設置

任何建議，建議將不勝感激。我正在使用.... Django正式版。 1.5.1我使用PIP和Python 2.7.2安裝

    RuntimeError: maximum recursion depth exceeded in cmp

UPDATE：所以我落得這樣做是爲了做安裝VirtualBox的，就可以安裝免費的Ubuntu，然後移動到完成的矯枉過正教程...哦，好！

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

問題出在functools.py文件中。這個文件來自Python。我剛安裝了一個新版本的python 2.7.5，這個文件是錯誤的（我有另一個 - python 2.7.5的老版本安裝，那裏的文件functools.py是正確的）

要解決這個問題，替換這個關於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)] 
}

只有在互聯網上爲我工作的解決方案。爲什麼這不被標記爲答案？謝謝，救了我幾個小時的挫折。 – 2015-06-26 08:30:45

也適合我！當我更新到Django 1.9時出現了這個錯誤。謝謝。 – juanifioren 2015-12-11 19:29:08

在更新到Django 1.9之前爲我工作。謝謝。 – 2016-03-30 11:31:15

你有可能遇到這樣的錯誤：http://bugs.python.org/issue10042

究竟發生了什麼，很難說沒有調試，有點我猜的事情，應該是一個字段一個不在這一行：

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

謝謝Lennart對我來說是一個很好的開始。我不知道從哪裏開始。 – 2013-04-28 06:17:53

今天我在這裏有這個問題。

我們也使用django1.5.1和python2.7.2。

起初，我們安裝了django1.4，它工作，但該項目具有django1.5功能，所以它不是一個完整的解決方案。我們安裝了python2.7.5，它工作的很好！

歡迎來到StackOverflow！下次嘗試在評論部分發布這個內容，因爲它不是一個完整的編碼解決方案。謝謝 – cdomination 2016-07-26 11:41:19
