轮播不工作 - 引导

Question

我无法从第一张图片更改为第二张图片，它也不会在它们之间自动滑动。我究竟做错了什么？所以基本上我希望能够手动滑动以将图片更改为下一张，如果我不这样做，它会在一段时间后自动滑动。有人愿意看一下并告诉我这段代码有什么问题吗？同样由于某种原因，当我尝试先加载 jquery 时，控制台中出现错误提示：

bootstrap.min.js:6 未捕获的错误：Bootstrap 的 JavaScript 需要 jQuery(…)

我的代码：

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

    <!-- Wrapper for slides -->
    <div class="carousel-inner" role="listbox">

      <div class="item active">
        <img src="images/1.jpg" alt="Chania" width="460" height="345">
        <div class="carousel-caption">
          <h3>Chania</h3>
          <p>The atmosphere in Chania has a touch of Florence and Venice.</p>
        </div>
      </div>

      <div class="item">
        <img src="images/2.jpeg" alt="Chania" width="460" height="345">
        <div class="carousel-caption">
          <h3>Chania</h3>
          <p>The atmosphere in Chania has a touch of Florence and Venice.</p>
        </div>
      </div>

      <div class="item">
        <img src="images/3.jpg" alt="Flower" width="460" height="345">
        <div class="carousel-caption">
          <h3>Flowers</h3>
          <p>Beatiful flowers in Kolymbari, Crete.</p>
        </div>
      </div>

      <div class="item">
        <img src="images/4.jpg" alt="Flower" width="460" height="345">
        <div class="carousel-caption">
          <h3>Flowers</h3>
          <p>Beatiful flowers in Kolymbari, Crete.</p>
        </div>
      </div>

    </div>

    <!-- Left and right controls -->
    <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
      <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
      <span class="sr-only">Next</span>
    </a>
  </div>
</div>

您必须在添加引导 javascript 之前添加 jQuery。。

例如：
