轮播无法正常工作。我已经检查了几次代码，但是似乎我不知道为什么照片之间没有过渡

我曾尝试将轮播添加到我的网页，但是以某种方式仅显示活动照片。照片集没有过渡。

<div class="container">
  <div id="main-slider" class="carousel slide" data-ride="carousel">
    <ol class="carousel-indicators">
      <li data-target="#main-slider" data-slide-to="0" class="active"></li>
      <li data-target="#main-slider" data-slide-to="1"></li>
      <li data-target="#main-slider" data-slide-to="2"></li>
    </ol>
    <div class="carousel-inner" role="listbox">
      <div class="carousel-item active">
        <img src="img/slide_01.jpg" class="d-block img-fluid" alt="">
      </div>
      <!--carousel item-->
      <div class="carousel-item">
        <img src="img/slide_02.jpg" class="d-block img-fluid" alt="">
      </div>
      <div class="carousel-item">
        <img src="img/slide_03.jpg" class="d-block img-fluid" alt="">
      </div>
    </div>
    <a href="#main-slider" class="carousel-control-prev" data-slide="prev">
      <span class="carousel-control-prev-icon" aria-hidden="true"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a href="#main-slider" class="carousel-control-next" data-slide="next">
      <span class="carousel-control-next-icon" aria-hidden="true"></span>
      <span class="sr-only">Next</span>
    </a>

  </div>
</div>

单击“ carousel-control-next”按钮，应更改三张照片集“ slide_01.jpg”，“ slide_02.jpg”，“ slide_01.jpg”。

确保您已包含所有必要的库，以使轮播能够正常工作。

如果您使用的是Bootstrap v4.2，则需要以下内容

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css">
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/js/bootstrap.min.js"></script>

我复制了您的HTML代码，它起作用了...

请参见下面的演示

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css">
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/js/bootstrap.min.js"></script>
