Okay - i found a fix but it would be great to get this validated by someone

I removed the python -> python3 alias from zsh to avoid namespace clashes

I created a virtual env called venv with the following

python3 -m venv venv 

which created a venv folder in the root of my project.

I activated this with

. venv/bin/activate

and then had to reinstall django and django ninja

pip install django django-ninja

I was then able to run the runserver command

./manage.py runserver

This all seems fine to me (although it does mean that I have a virtual environment folder in my project which seems like I should add this to the .gitignore file) - does anyone have any thoughts please?

Thanks
