我能够部署在Heroku上创建和部署Django应用。我的应用程序在本地运行。但是当我运行heroku open时，我得到了默认错误消息

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "allistic_server.settings")
我可以看到您的项目被称为allistic_server，但是在procfile中，您提到了“ server.wsgi”，这不是有效路径。改变这个
web:gunicorn server.wsgi --log-file
到
web:gunicorn allistic_server.wsgi --log-file
