使用uvicorn启动django时引发了以下错误

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

原因及解决

1.原因: 排查了很久,最后发现报错来源于包的导入

在__init__.py文件中用了下图所示的包导入语句, 导致了uvicorn无法启动django, 如下图:

2.解决:

移除放置在__init__.py中的导入语句, 在需要使用这个包的py文件中重新导入包,最后可正常启动django, 如下图

导入:

正常启动:

确定要放弃本次机会？
