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.

解决方法如下： 在代码文件的最上方，添加如下代码：

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