对不起，但我不知道发生了什么事，当我试图运行（python3 manage.py makemigrations）。
我真的不知道是怎么回事我找了一会儿答案但我想不出错误在哪里：

(paginas) root@janstar:/home/paginas/proyectodedjango# python3 manage.py makemigrations

During handling of the above exception, another exception occurred:

在错误消息中，它说你需要一个字符串而不是'PosixPath'尝试将路径变成字符串。

您也可以用途：

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

简单地你可以试试这个办法：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}

在settings.py文件中添加上述代码后，首先需要删除db文件，并删除每个应用程序的所有migration folders，然后运行以下命令：

python manage.py makemigrations appname

python manage.py sqlmigrate appname 0001

python manage.py migrate

现在你的问题就解决了。
