Yes, I believe dateutil is the problem. It is not installed by default on Mac or Windows systems (and possibly some Linux distributions as well). I'm updating the documentation to reflect this.
Please run pip install python-dateutil
from django-json-field.

The issue was caused by an internal compatibility issue with gettext() and South, which I just fixed.
Thanks for the report! Let me know if you are still having issues after updating.

Unfortunately even after updating (I did pip uninstall django-json-field and then pip install -e git+git://github.com/derek-schaefer/django-json-field.git#egg=json_field) I still get the same errors.
It doesn't look like the problem is related to south, because I can't even import json_field from Django shell:
(test)Dae-MacPro:test Dae$ python manage.py shell
Python 2.7.3 (v2.7.3:70274d53c1dd, Apr 9 2012, 20:52:43)

>>> from json_field import JSONField
Traceback (most recent call last):
File "<console>", line 1, in <module>
ImportError: cannot import name JSONField
At the same time just import json_field seem to work (so no "no module named ..." error).
More like I did something wrong... (I'm new to Django, sorry!)

It looks like you did everything correctly and have your virtualenv running, so I'm not sure what the problem might be.
The only thing I can think of is that another import error is happening down the line. Try editing json_field/__init__.py and removing the try/except block. Maybe that will provide more information.

Unfortunately the error was the same when I removed the try/except block from __init__.py
I decided to try a new virtualenv and it's the same. Here's the full log:

Can you try running import dateutil? I assumed it was included in all Python distributions but perhaps that is not the case.
from django-json-field.

THANK YOU!
pip install python-dateutil has indeed fixed the problem!
However, I went through south migrations, even did runserver and now stuck at
'module' object has no attribute 'JSONDecodeError'
Django Version: 1.4
Exception Type: AttributeError
Exception Value:
'module' object has no attribute 'JSONDecodeError'
Exception Location: /Users/Dae/.virtualenvs/booker/src/json-field/json_field/fields.py in to_python, line 100
:(

Even though Django includes a basic version of simplejson it doesn't seem to include the JSONDecodeError class. Run pip install simplejson and try again. I'll try to make this more flexible.

Thank you so much, Derek!

No problem! Also, I just updated the code to remove the unintended dependency on simplejson so you should be alright now in either case.
