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 also tried upgrading kombu but it is still giving the error.The full traceback is added below-
rishav#Swastik:~/open-event-orga-server$ sudo python create_db.py
Traceback (most recent call last):

Answer 1

This solved my problem:
Downgraded kombu to 2.5.16.
Reinstalled django-celery
here is log:

Answer 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...

Answer 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 key
print(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 key
print(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)])
