django.core.exceptions.ImproperlyConfigured：请求的设置LOGGING_CONFIG，但未配置设置

我正在尝试运行一个填充脚本，该脚本是从tango_with_django教程（ https://github.com/leifos/tango_with_django/blob/master/tango_with_django_project/populate_rango.py ），但是我得到了以下追溯，它似乎与Django 1.7中的更改有关？如果有人能解释我在做什么错，我将不胜感激。

I'm trying to run a populate script which I put together from the tango_with_django tutorial (https://github.com/leifos/tango_with_django/blob/master/tango_with_django_project/populate_rango.py) however I'm getting the below traceback and it seems to be related to changes made in Django 1.7? I'd appreciate if someone could explain what I'm doing wrong here.
