I'm trying to import json_util in my environment file:

from bson import json_util

I get this import error: no module named bson.

I tried to pip install and uninstall pymongo and bson - but nothing seemed to help. I found out that the bson package is included in pymongo so I installed it explicitly and then I received an EPOCH_AWARE import error.

Currently, only pymongo is installed. It works when I force the virtual environment by using this line: 

#subprocess.Popen(['/home/.virtualenvs/simple_worker/bin/python', fileName])

But when I try to run it through the os like this:

os.system('PYTHON_ENV=%s python %s' % (env, fileName))

I get this import error on bson.

Edit: Here is the pip list output

(simple_worker) ➜ worker  pip list                                                                                         ✭ ✱

    Which OS are you running at? Did you try installing `bson` using pip as admin/super user? Are you working with virtualenv's or not? If so, did you activate it properly before running the code? – albert Feb 07 '16 at 15:02

    what happens if you import bson on repl , what is the output of pip list? – FabioCosta Feb 07 '16 at 15:10
  • @albert I'm runing on ubuntu. I tried installing bson using pip (as admin). I'm working with virtualenv and i activate it before pip install. – Liad Amsalem Feb 07 '16 at 15:29
  • In your terminal try `pip freeze` in order to get a list of all 'pip-installed' packages and have a look whether `pymongo` is installed correctly. – albert Feb 07 '16 at 15:33
  • Running ubuntu, installed with 'sudo pip install bson'. That worked but there's no json_util in it. I take you must use the version of bson in MongoDB to get json_util – Keith Brodie Feb 07 '16 at 15:34
  • @FabioCosta pip list added to the question – Liad Amsalem Feb 07 '16 at 15:37
  • Did you install something `pymongo`-related using `apt`? There might be some incompatibilities: http://stackoverflow.com/a/16004833/3991125 http://www.openjems.com/pymongo-import-problem/ http://api.mongodb.org/python/current/installation.html – albert Feb 07 '16 at 15:44

If you don't get the no module named bson error but the EPOCH_AWARE import error , this is due to a name clash between bson and pymongo . In this case you should do these in order :

sudo pip uninstall bson
sudo pip uninstall pymongo
sudo pip install pymongo

you don't need to install bson again

  • tks, this error happened to me the same, supposed to use module pymongo instead of bson – Dee Nov 23 '20 at 09:54

Please try on your terminal:

sudo apt-get purge python-bson
sudo apt-get install python-bson

I had used both pymongo and bson in my code, and I've had the same error no module named bson.
I first tried to install bson but it didn't work, so I uninstalled it again, then tried to re-install pymongo and it worked for me. I've used the following commands.
if you've installed bson, uninstall it:

pip uninstall bson

and uninstall then install pymongo again:

pip uninstall pymongo
pip install pymongo
