django.core.exceptions.AppRegistryNotReady：モデルはまだロードされていません.- django 1.11

Question

DRFを使用してトークン認証を実装しようとすると、私の端末でこのエラーが発生します。私は他の関連のrelevant questions with solutionsを見たことがありますが、それらのどれもが私の問題を解決しませんでした。

以下

私wsgi.py

""" 
WSGI config for myApp project. 

It exposes the WSGI callable as a module-level variable named ``application``. 

For more information on this file, see 
https://docs.djangoproject.com/en/1.11/howto/deployment/wsgi/ 
""" 

import os 

from django.core.wsgi import get_wsgi_application 

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myApp.settings") 

application = get_wsgi_application()
