django heroku中的静态文件问题

Question

我在 django 中遇到了这个静态文件的问题。我成功地将 django 应用程序部署到 heroku 并且该站点在 https://timon-webchat.herokuapp.com/ 中工作，但是您如何在没有任何样式或图像的情况下查看。但是如果运行 python manage.py runserver local 一切都很好，我可以看到样式、js 代码和图像 请告诉我这里有什么问题是我的 settings.py 文件：

在目录 statifiles 我有目录：css、js、admin、app_chat 我有我的样式 js 代码和图像。那我做错了什么？

为了让 Django 处理你的静态文件，你应该运行python manage.py collectstatic。 Heroku 应该已经为你做了这个。 Heroku 不会自动为您的静态文件提供服务，这就是为什么我建议您使用 whitenoise 包的原因。它允许您的 Django 应用自动提供静态文件，而无需额外配置。

在此处查看 Django 文档：http://whitenoise.evans.io/en/stable/django.html

还将whitenoise 添加到您的requirements.txt
