Я не могу выполнить миграцию в следующий файл? ⇐ Python

[Anonymous]

Я пытаюсь создать миграцию следующего кода models.py, но возникает следующая ошибка ???(Я изучаю веб-разработку на курсе CS50-Web Devlopment)
Может ли кто-нибудь помочь мне решить ошибку: у меня очень мало знаний о django, sqlite, а также о веб-разработке.
from django.db import models
class Flight(models.Model):
origin = models.CharField(max_length=64)
destination = models.CharField(max_length=64)
duration = models.IntegerField()


Ошибка следующая:
