Heroku build django应用程序不'；如果DEBUG=False，则不创建静态根目录。为什么，里面是什么？

heroku上的Dajango（+channels/postgres/redis）应用程序，DEBUG=True，运行良好，无错误，无异常。如果DEBUG=False，那么它实际上根本不起作用，error500。有没有线索说明调试标志是如何以这种方式参与的？多谢各位

Heroku日志示例，DEBUG=True（正常工作）：

获取路径=“/”

“GET/HTTP/1.1”302

“GET/accounts/login/？next=/HTTP/1.1”200

显示登录页面，确定

现在的问题是：唯一的区别是DEBUG=False：

获取路径=“/”

用户警告：在：/app/pickupteaming/staticfiles处没有目录/

“GET/HTTP/1.1”302

“GET/accounts/login/？next=/HTTP/1.1”500

Heroku日志示例详述如下：

当您将DEBUG=FALSE设置为生产模式时，Django将不会像在开发模式中那样为静态文件提供服务，因为它效率低下且不安全。您需要安装WhiteNoise并对setting.py文件进行一些调整。通过以下方式查看此优秀指南：
