    from django.utils import six, timezone
ImportError: cannot import name 'six' from 'django.utils' (d:productionmyprojectvenvlibsite-packagesdjangoutils\__init__.py)

I have checked in folder Libsite-packagesdjangoutils and not found and six.py file but still from Libsite-packagesjsonfieldencode.py containing line from django.utils import six, timezone which trying to import six but not able to find.

Earlier version of django containing six.py file in folder Libsite-packagesdjangoutils.

Any idea how to solve this ?

Short answer: you might want to abandon django-jsonfield.

Based on the traceback, you are using the django-jsonfield package [GitHub], and this is a known issue [GitHub-issue]. It depends on the django.utils.six module, but that module has been removed in .

At the moment, you thus can not use with , and since the last commit to this project is from October 2017, perhaps the project is not that "active" anymore, and it thus might take a very long time (or even never) get fixed. The successor of is ([GitHub]). It was made compatible with by a pull request in October (2019) [GitHub-pr].
