ImportError: cannot import name JSONField

I haven’t managed to install the package.

#settings.py
INSTALLED_APPS = (
...
    'json_field',
...
)

#models.py
from json_field import JSONField

from django.db import models

...

class Human(models.Model):
    phone_numbers = JSONField()

and when doing south migration:

  File "<...>/models.py", line 2, in <module>
    from json_field import JSONField
ImportError: cannot import name JSONField

I tried Django shell

(test)Dae-MacPro:test Dae$ python manage.py shell

>>> from json_field import JSONField
Traceback (most recent call last):
  File "<console>", line 1, in <module>
ImportError: cannot import name JSONField

I’m using Django 1.4. I tried installing from repo and pip, no difference.

What might be the problem?

Thanks

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

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