Django Admin MakeMigrations Error - ROOT_URLCONF is not configured

Question

I'm having this error when I trying to push django-admin makemigrations from cmd in my project folder. I can not find the exact problem in other topics. I'm quite sure that I'm doing well till here. I really appreciate your helps in advance.

There is the error

django.core.exceptions.ImproperlyConfigured: Requested setting ROOT_URLCONF, but settings are not 
configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call 
settings.configure() before accessing settings.

There is my urls.py module

from django.contrib import admin
from django.urls import path, include
from apps.crm import views as crm_views

urlpatterns = [
path('admin/', admin.site.urls),
path('', crm_views.home, name = 'home'),
path('about/', crm_views.about, name = 'about'),
]

There is my wsgi module

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

There is my settings module
