I have a django project that I am trying to connect with a postgres database. However when I try to run the command python manage.py makemigrations I get the following error:

I found that this does not work because I was using python 3.9 as a interpreter. In PyCharm, I created a new interpreter, setting the base interpreter as python 3.7 and reinstalled all my needed packages it worked as expected
