Python 图像不是'；使用Heroku启动网站时不加载。我该如何解决这个问题？

当我部署*我的heroku网站时除了我的之外，所有的都加载了，你可以看到所有的东西，但是它显示的图像是错误的。我不知道如何解决这个问题。我被这个问题困扰了将近2天。如果你知道如何解决它，请向我解释一下，以便将来我可以回去看看这个问题并解决我的问题问题我确实具备了与heroku一起启动我的网站的所有要求，但我根本看不到这些图片

您还没有运行

python3 manage.py collectstatic--没有输入

，这就是为什么没有为WhiteNoise提供静态文件的原因请看您能否进一步解释我不知道您刚才说了什么我已经完成了设置的所有步骤。py我需要在manage.py上做什么。谢谢！比如你是什么意思我需要python3 manage.py collectstatic--无输入？？？请提供完整的构建日志，

python3 manage.py collectstatic--在构建过程中不应运行任何输入来收集静态文件，以便whitenoise提供服务
