setting s文件已经修改过了，在网上也找了好多方法，都没用，哪位大神救救我，太折磨了，放张老婆
django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

在你程序最上方，添加下面的代码
import os,django
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project_name.settings")# project_name 项目名称
django.setup()
