3_ImproperlyConfigured Requested setting DEFAULT_INDEX_TABLESPACE, but settings

问题描述

在IPython环境中导入Django项目中的类时报如下错误

ImproperlyConfigured  Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

可能存在的问题

• 1、项目的路径不在sys.path中，也就是python搜索库的路径列表中，其实就认为是Python的环境变量吧
• 2、根据提示应该是缺少某些配置

解决方法如下
