Answer 1

这解决了我的问题：

将海带降级为2.5.16。
重新安装django-celery

这是log：

Answer 2

我在kombu 4.0.x的python 2.7.8上遇到了同样的问题，我通过将kombu降级到3.0.x（这是我需要的版本）解决了这个问题。

没有时间调查问题的原因，但this可能有关......

Answer 3

如果ImportError导入不正确（例如使用orderedDict，Ordereddict或ordereddict），也会发生：

方法1

from collections import OrderedDict

d = {'banana': 3, 'apple': 4, 'pear': 1, 'orange': 2}

# dictionary sorted by key
print(OrderedDict(sorted(d.items(), key=lambda t: t[0])))
print(OrderedDict([('apple', 4), ('banana', 3), ('orange', 2), ('pear', 1)]))

方法2

import collections

d = {'banana': 3, 'apple': 4, 'pear': 1, 'orange': 2}

# dictionary sorted by key
print(collections.OrderedDict(sorted(d.items(), key=lambda t: t[0])))
print(collections.OrderedDict(
    [('apple', 4), ('banana', 3), ('orange', 2), ('pear', 1)]))

输出

OrderedDict([('apple', 4), ('banana', 3), ('orange', 2), ('pear', 1)])
OrderedDict([('apple', 4), ('banana', 3), ('orange', 2), ('pear', 1)])
