我正在练习 Django，但是当我发出命令时python manage.py makemigration，python manage.py migrate我得到了一个错误，如标题所示。下面提到了完整的错误：

似乎设置DATABASES - NAME需要一个字符串，而不是一个Path对象。

在您的设置中尝试更改此行

'NAME': BASE_DIR / 'db.sqlite3',

到

'NAME': str(BASE_DIR / 'db.sqlite3'),

所以这NAME是一个字符串而不是一个Path.

错误来自这行代码django/db/backends/sqlite3/creation.py#L13，似乎此提交解决了问题，因此Django v3.1.1无需再使用'NAME': str(BASE_DIR / 'db.sqlite3'),，只需使用就'NAME': BASE_DIR / 'db.sqlite3',足够了。

我通过将文件中数据库名称的行更改settings.py为：

'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),

我有一个类似的问题，我通过将文件的所有者更改为当前所有者并使用以下命令启动服务器来解决sudo -u <user_name> python3 manage.py runserver。似乎是权限问题。
