如何使滚动和旋转木马一起工作？

Question

我成功地启动了bootstrap 4滚动条。我也有一个Bootstrap 4轮播工作。但是，当我将它们放到一个索引文件中时，轮播似乎取消了滚动浏览，并且完全停止工作。

我非常新手，无法弄清楚如何让他们一起工作。我在想与javascript有关。他们互相压倒了吗？

   <div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
    <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="3"></li>
</ol>

<div class="carousel-inner">
    <div class="carousel-item active">
        <img class="d-block w-90" src="images/slide1.jpg" alt="First slide">

    </div>
    <div class="carousel-item">
        <img class="d-block w-90" src="images/slide2.jpg" alt="Second slide">
    </div>
    <div class="carousel-item">
        <img class="d-block w-90" src="images/slide3.jpg" alt="Third slide">
    </div>
     <div class="carousel-item">
        <img class="d-block w-90" src="images/slide4.jpg" alt="Third slide">

</div>
<a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
