我收到错误

ImportError：无法导入名称 OrderedDict

在我的 ubuntu 14.04 机器上本地安装服务器时。
我已经尝试手动安装orderdict，也尝试升级kombu，但它仍然给出错误。完整的回溯添加在下面-

rishav@Swastik:~/open-event-orga-server$ sudo python create_db.py
Traceback（最近一次调用最后）：文件“create_db.py”，第 5 行，
从应用程序导入 current_app
文件“/home/rishav/open -event-orga-server/app/ init .py”，第 23 行，
从 celery 导入 Celery
文件“/usr/local/lib/python2.7/dist-packages/celery/init .py ”，第 133 行，在
from celery import 5 # noqa File "/usr/local/lib/python2.7/dist-packages/celery/five.py", line 153, in
from kombu.utils.compat import OrderedDict # noqa
ImportError: cannot import name OrderedDict

这解决了我的问题：

  1. 将 kombu 降级到 2.5.16。

  2. 重新安装 django-celery

这是日志：

我在带有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，但这可能是相关的......

ImportError如果未正确导入（例如 with orderedDict、Ordereddict或） ，也会发生ordereddict：

方法一

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)]))

方法二

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)])

资源

8.3.5.1。OrderedDict 示例和食谱
