我在Bootstrap 5导航栏中的切换按钮无法正常工作。按钮出现，但单击它不会在较小的屏幕上显示导航链接。我已经遵循了Bootstrap文档和示例，但我似乎无法找出问题所在。

`<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-      target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-      label="Toggle navigation">
   <span class="navbar-toggler-icon"></span>
  </button>
 <di`your text`v class="collapse navbar-collapse" id="navbarSupportedContent">
  <ul class="nav navbar-nav me-auto mb-2 mb-lg-0">
    <li class="nav-item">
      <a class="nav-link active" aria-current="page" href="#">Home</a>
    </li>
    <li class="nav-item">

    </li>
    <li class="nav-item dropdown">
