ModuleNotFoundError: No module named 'mysite' when try to call django-admin

when I run the command django-admin collectstatic in terminal i'm getting the following error:

ModuleNotFoundError: No module named 'mysite'

it even appears at the end of the list django-admin commands help

Type 'django-admin help <subcommand>' for help on a specific subcommand.
Available subcommands:

[django]
    check
    compilemessages
    createcachetable
    dbshell

Note that only Django core commands are listed as settings are not properly configured (error: No module named 'mysite').

setting.py

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
WSGI_APPLICATION = 'mysite.wsgi.application'

wsgi.py

import os
from django.core.wsgi import get_wsgi_application
    
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
application = get_wsgi_application()

instead of django-admin collectstatic use this command

python manage.py collectstatic
