MongoKit “ImportError: No module named objectid ” error

问题

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?

回答1:

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

回答2:

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
