我正试图创建以下models.py代码的迁移，但出现了以下错误？？？(我正在学习CS50网络开发课程中的网络开发(有人能帮我解决这个错误吗？我对django、sqlite以及Web开发知之甚少。

from django.db import models
class Flight(models.Model):
origin = models.CharField(max_length=64)
destination = models.CharField(max_length=64)
duration = models.IntegerField()

Answer 1

您从错误的模块导入include。可能来自xml.etree.ElementInclude

所以改变

from xml.etree.ElementInclude import include

至

from django.urls import include

在您的airline/urls.py文件中。
