Getting Importerror: Cannot Import Name Ordereddict

I am getting the error ImportError: cannot import name OrderedDict while installing a server locally on my ubuntu 14.04 machine.I have tried installing ordereddict manually and

Solution 1:

This solved my problem:

1. Downgraded kombu to 2.5.16.

2. Reinstalled django-celery

here is log:

Solution 2:

I had this same problem on python 2.7.8 with kombu 4.0.x and I solved it by downgrading kombu to 3.0.x (which was the version I needed).

Didn't have time to investigate the reason of the issue, but this might be related...

Solution 3:

The ImportError would also occur, if it is not correctly imported (such as with orderedDict, Ordereddict, or ordereddict):

Method 1

from collections import OrderedDict

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

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

Method 2

import collections

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

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

Output

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