每当我运行服务器或在终端中执行任何命令时，都会在终端中显示此错误。服务器正在运行并且网页工作正常，但是当我退出服务器或运行任何命令(如 python manage.py migrate)时，会显示此错误。

我通过更改 settings.py 文件中的 DATABASES 清除了此问题:
改变

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

到

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

这有效

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': str(os.path.join(BASE_DIR, "db.sqlite3"))
    }
}
