But if I activated my virtual environment and run with python manage.py runserver 0.0.0.0:8000 it works well and all is good so what is the problem here, is it python version compatibility

Update ----------

I tried the answer of this question of stackoverflow and in vain

Could be Python version, some library problem or something else. But what I can tell you is that when you use manage.py runserver you are not using Apache & WSGI at all - so one can work where the other doesn't. — manassehkatz-Moving 2 Codidact

This error arises because your mod_wsgi is compiled for Python 2.7, but you have pointed it at a Python virtual environment and code which is Python 3.X. The keyword only syntax does not exist in Python 2.7.

You need to install mod_wsgi which has been compiled against Python 3.X version you want to use. You cannot force mod_wsgi compiled for one version to use a Python virtual environment for a different Python version.

You can use the checks in:

http://modwsgi.readthedocs.io/en/develop/user-guides/checking-your-installation.html

to verify what version of Python your mod_wsgi is compiled for.

Also review:

http://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html

for the recommended way of using a virtual environment with mod_wsgi. You currently don't use the recommended way.
