django 第一次运行出错

直接运行整个项目正常，直接运行url文件报错

报错内容：

% (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.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.

解决方案：

在代码开始出添加：

import os,django
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "ceshiweb.settings")# project_name 项目名称
django.setup()
