Django make migrations返回ModuleNotFoundError

Question

我刚刚开始通过在线讲座学习Django，我正在尝试运行这个命令

python3 manage.py makemigrations

它返回以下错误

Traceback (most recent call last):

ModuleNotFoundError: No module named 'flights.url'

我已经检查以确保Python和Django是最新的，并且我在INSTALLED_APPS中安装了正确的应用程序

我假设您的项目/ urls.py中的urls.py文件拼写错误

path('flights/', include('flights.urls'))
