问题描述

使用 bootstrap v5.0 和以下导航栏设置新站点

<nav class="navbar navbar-expand-md navbar-dark fixed-top">
    <a class="navbar-brand font-orbitron" href="/">
        <img src="/static/images/binoculars.png" alt="Logo" class="nav-logo">
    </a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExample04" aria-controls="navbarsExample04" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>

    <div class="collapse navbar-collapse" id="navbarsExample">

            <li class="nav-item dropdown">
                <a class="nav-link dropdown-toggle" href="#" role="button" data-bs-toggle="dropdown" aria-expanded="false">
                  Dropdown
                </a>
                <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
                  <li><a class="dropdown-item" href="#">Action</a></li>
                  <li><a class="dropdown-item" href="#">Another action</a></li>
                  <li><hr class="dropdown-divider"></li>
                  <li><a class="dropdown-item" href="#">Something else here</a></li>
                </ul>
            </li>
        </ul>
    </div>
</nav>

当我单击下拉切换时，我收到此错误
