当DEBUG = false时，静态文件在部署到Heroku时（但在本地服务器中）不会加载吗？

Question

我一直在搜索StackOverflow搜索解决方案，但它们似乎都没有工作。当我将它部署到Heroku时，我无法加载我的Django Web应用程序的静态文件。它在localhost：8000中工作正常。这只是在我设置DEBUG = False时。它在DEBUG = True时工作正常。我的静态文件基本上由主页的几个图像和1个CSS文件组成。

我的主要项目目录是 mynotes 。

我的应用目录是 mynotess 和用户

    ] #I copied (sort of) this from the Django documentations but it still doesn't work.

静态文件（jpg，png，CSS）包含在名为＆＃39; static＆＃39;的目录中。在我的app目录（ mynotess ）。

任何形式的帮助将不胜感激。我已经尝试过StackOverflow上的每个解决方案，但似乎没有任何解决方案可行。这在DEBUG为真时工作正常，并且只有在DEBUG为假时才会崩溃。即便如此，它仍然适用于localhost。我忘了在这里做点什么吗？
