为什么 Bootstrap 中的轮播控件无法正常工作?

Why are the controls for my carousel in Bootstrap not functioning?

主要问题如标题所述。显示器工作正常,我可以正常看到图像,但下一个和上一个按钮以及轮播指示器不起作用。似乎没有任何错误消息,我已经尝试安装 poppers,但似乎也没有用。如果有任何帮助,我将不胜感激!

我的代码如下:

data-*属性在Bootstrap5中被data-bs-*替换了。所以对于Bootstrap5,代码将是这样的—— 示例:

<button class="navbar-toggler" data-bs-toggle="collapse" data-bs-target="#navbar">
