Bootstrap 4 Carousel 控制按钮不工作

如何解决Bootstrap 4 Carousel 控制按钮不工作

我不确定我做错了什么，但由于某种原因，bootstrap 4 carousel 控件无法正常工作，如果有人可以提供帮助，我将不胜感激。我已经玩了大约一个小时的代码，所以我想我会得到第二个意见，看看发生了什么。

我查看了引导程序文档，然后复制并粘贴了控件。我看了看课程，一切看起来都一样

解决方法

ID 不同。

更改为

    <!-- Left and right controls -->
             <a class="carousel-control-prev" href="#carouselExampleControls" data-slide="prev">
          <span class="carousel-control-prev-icon"></span>
