I have a Django project that i'm trying to set up unit testing with tox in.
here is the directory structure:
+ djangoProject

+-.github
+-.pytest
+-.tox
+- api
+- blog
+- djangoProject
+- templates

+ .gitignore
+ manage.py
+ pyproject.toml
+ requirements.txt
+ requirements_dev.txt
+ setup.cfg
+ tox.ini
Here are the various config files

their is multiple problems here
1: both py38 envs don't use my requirements and instead run pip with --no-deps and goes after some file that doesn't exist
2: in py38 envs the wheel fails to build - this is probably because of #1 but I'm not sure.
3: In all other envs the wheel for psycopg2 fails to build and it also fails to install using setup.py
I have tried removing lines from the tox.ini to get a different output to try and locate the issue if it was in the ini files but found nothing.
when I add things to my project with pip manually or using PyCharm's package manger inclduing psycopg2 it all works fine so I don't know why it wont work in tox
I don't know what I'm doing wrong
I was working off this tutorial video: https://www.youtube.com/watch?v=DhUpxWjOhME
it's not for a Django project but everything before the tox part I was able to get running fine
The problem is well described in the error log:

So you fail to build the psycopg2 package, because...

./psycopg/psycopg.h:35:10: fatal error: Python.h: No such file or directory
35 | #include \<Python.h\>
... pip tries to install the source package, which needs some compilation step for this the mentioned header file is missing.
When I try to reproduce the issue...
pip install psycopg2
Collecting psycopg2
Downloading psycopg2-2.9.3.tar.gz (380 kB)
...
You clearly see, that psycopg2 is downloaded as source and not as wheel.
So this is not a tox issue, but rather the project does not provide a pre-compiled wheel, and your environment is missing the necessary requirements.
There is the question left why this would work in your PyCharm environment. This is nothing I can say for sure, but one possible issue could be that your PyCharm is running in a different environment than tox - as you mentioned you are working in a VM environment. So this is something you need to figure out yourself.
