Issue with importing rest_framework inside django app - django

Question

I am facing an issue of importing rest_framework inside my django app whenever i try to make migrations or create superuser or simply run the runserver.
I have installed the framework using this command but django still doesn't recognize it
sudo pip install djangorestframework
here's the snippet of settings.py file:
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'rest_framework',
'companies.apps.CompaniesConfig',
]
REST_FRAMEWORK = {
'DEFAULT_MODEL_SERIALIZER_CLASS':
'rest_framework.serializers.HyperlinkedModelSerializer',
# Use Django's standard `django.contrib.auth` permissions,
# or allow read-only access for unauthenticated users.
'DEFAULT_PERMISSION_CLASSES': [
'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'
]
}
Output:
Traceback (most recent call last):
