报错信息：django.core.exceptions.ImproperlyConfigured: Requested setting LOGGING_CONFIG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
解决办法：
在文件加入以下代码：
import os,django
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "HelloWorld.settings")# project_name 项目名称
django.setup()
具体问题我也不是很清楚
