如何解决当 Cpanel 上的调试为 False 时，Django 媒体文件未加载
我试图展示我的媒体文件一个多星期，并尝试了所有 stackoverflow 解决方案，但一无所获。我的项目托管在 Cpanel 上，我尝试为媒体提供绝对路径，尝试将它们放在 public_html 文件夹中，什么也没有。另外我的静态文件没有问题，但媒体文件甚至没有显示在开发人员工具的源代码中（在正常情况下应该有一个），当调试为真时，它工作得很好，但当调试为假时，它确实如此不是。请问有什么想法吗？

解决方法
您不能使用白噪声为您的媒体文件提供服务：https://github.com/evansd/whitenoise/issues/62 您需要将您的服务器配置为让 apache 或 nginx 或类似的东西为您的媒体目录中的这些媒体文件提供服务。
