在修改Django代码时遇到了错误。
虽然不知道发生错误的具体原因，但总算修复好了，作为备忘录留下来。

在创建应用程序或迁移时遇到了错误。
以下是错误信息。

$ python manage.py startapp reviews

TypeError: argument of type 'PosixPath' is not iterable

当使用Pathlib库时，返回的类型似乎是PosixPath，而这引发了类型错误。

据说将此path对象转换为str类型会更好。

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

#変更後
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': str(BASE_DIR / 'db.sqlite3'),
    }
}
