我可以部署在Heroku上创建和部署Django应用程序。我的应用在本地运行。但是当我运行heroku时，我收到了默认的错误消息
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details.

我可以看到你的项目被称为allistic_server，但在procfile中你提到了'server.wsgi'这不是一个有效的路径。改变这个
web:gunicorn server.wsgi --log-file
至
web:gunicorn allistic_server.wsgi --log-file
