MongoKit "ImportError: No module named objectid " error


Question

I get some very strange error using MongoKit:

>>> from mongokit import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/mongokit/__init__.py", line 35, in <module>
    from document import Document, ObjectId
  File "/usr/local/lib/python2.7/dist-packages/mongokit/document.py", line 48, in <module>
    from pymongo.objectid import ObjectId
ImportError: No module named objectid

I tried everything to find the reason but nothing helps. Actually I googled "ImportError: No module named objectid" error and it has no results at all. I tried to use MongoKit following the simple tutorial http://namlook.github.com/mongokit/introduction.html#a-quick-example and the first line of the tutorial produces this strange error. Below is the log of MongoKit installation.

What I'm doing wrong?

Accepted Answer

It's an error in the dependencies. As of PyMongo 1.11 objectid lives in the bson module, not pymongo.

As Electro said, it's a Bug.

I used the following dirty little hack to keep my site running until it is fixed:

import sys
import pymongo
import bson.objectid
pymongo.objectid = bson.objectid
sys.modules["pymongo.objectid"] = bson.objectid
