Django makemigrations 和迁移

Question

py manage.py makemigrations [project_name]我在使用and命令时遇到问题py manage.py migrate。每次我以正确的顺序尝试这两个命令时，都会收到以下错误：

Traceback (most recent call last):

  File "C:\Users\Gilbert\PycharmProjects\GGprojects\django\manage.py", line 20, in <module>

    main()

    return database_name == ':memory:' or 'mode=memory' in database_name

TypeError: argument of type 'WindowsPath' is not iterable

查看错误，我会说我的 Python 路径可能不正确。它的当前路径是C:\Users\Gilbert\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.9. 这是出现错误的原因吗？它会影响我的 Django 项目吗？另外，我该如何解决这个问题？

看起来它没有获取数据库路径。检查 settings.py 文件中的数据库名称。例如：对于 sqlite3，它应该是这样的：DATABASES = {&nbsp; &nbsp; 'default': {&nbsp; &nbsp; 'ENGINE': 'django.db.backends.sqlite3',&nbsp; &nbsp; 'NAME': str(os.path.join(BASE_DIR, "db.sqlite3"))&nbsp; &nbsp;}&nbsp;}如果这不适合您，请在此处分享您的数据库设置，以便我可以提供帮助
