Django

Всем привет! Не могу разобраться что за проблема, кто может объясните пожалуйста. На mac os создаю новый проект в django 2.0 версия python3.6, запускаю сервер, проект отображается в браузере, всё хорошо! Как только в новом проекте создаю новое приложение и пытаюсь запустить сервер то выдаёт ошибку:

Unhandled exception in thread started by <function check_errors..wrapper at 0x1041bcae8>

Объясните пожалуйста как это исправить!

В массиве INSTALLED_APPS хранятся все приложения из которых состоит проект, и там ты наверняка забыл подключить приложение one.
