Python, Django, Mongodb: ImportError: No module named bson.objectid [duplicate]

问题

I'm following this tutorial exactly. Tried deleting and restarting many times with virtualenv and I'm still getting errors. Is it python, mongodb and django supposed to be this frustrating to set up?

http://docs.mongodb.org/manual/tutorial/write-a-tumblelog-application-with-django-mongodb-engine/

I get a problem when I try to call

post.save()

I then get this error:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/models/base.py", line 460, in save

    from bson.objectid import ObjectId
**ImportError: No module named bson.objectid**

Please someone lead me in the right direction. Is there a better tutorial to follow because every single tutorial I follow I run into errors. I'm about to give up on pymongo and django...

回答1:

It looks like the environment isn't setup correctly. Can you ensure that pymongo is available in your python shell:

$> python.exe

Then in the shell:

>>> import pymongo
>>> pymongo.version

What version does that report?

Also try importing bson:

>>> import bson

If those work then make sure you are running your django mongodb-engine app in the same environment.
