On install I get an error when attempting makemigrations

[peircej]

I created a venv on Py3.8, activated that and installed the dependencies. When I call python manage.py makemigrations I get:

Traceback (most recent call last):

Hi @peircej,
Thanks for your feedback. Indeed a new version of Django could cause this problem.

I just made the fix and a new version of the tool is now available. You can retrieve changes and update project dependencies:

pip install -r requirements.txt

Note: dependency versions are now fixed to avoid such issues in the future.

Tell me if it works now and I can close this issue.
