windows 上 Celery 示例 Django 应用程序的递归问题

Question

我在尝试在我使用的 Django 上设置 Celery 时遇到问题 django example app

我使用以下命令设置 virtualenv

pip install virtualenv
virtualenv ..\env
call ..\env\Scripts\activate
pip install celery
pip install django

这给了我以下环境

amqp==1.4.9
anyjson==0.3.3
billiard==3.3.0.23
celery==3.1.23
Django==1.9.4
kombu==3.0.35
pytz==2016.3

并且在尝试通过命令启动 worker 之后

$ celery -A proj worker -l info

我遇到了运行时错误

RuntimeError: maximum recursion depth exceeded while calling a Python object

你知道我做错了什么吗？

Answer 1

问题出在 functools.py 文件中。
要解决此问题，请替换文件 functools.py 中的转换字典（关于 python\Lib\functools.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)]
}

到那个值

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)]
}
