来自 bootstrap 的导航栏未折叠

Question

我正在创建一个 React 应用程序并使用了 bootstrap 导航栏，但导航栏在移动视图中没有折叠，这看起来很烦人。

 <nav className="navbar fixed-top navbar-expand-lg navbar-dark bg-dark navbar-collapse">
          <div className="container-fluid">
            <Link className="navbar-brand" to="/">NewsMonkey</Link>
            <button className="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
              <span className="navbar-toggler-icon"></span>
            </button>
            <div className="collapse navbar-collapse" id="navbarSupportedContent">
              <ul className="navbar-nav me-auto mb-2 mb-lg-0">
                <li className="nav-item">
                  <Link className="nav-link active" aria-current="page" to="/">Home</Link>
                </li>
</nav>

这是导航栏的代码，请告诉实际问题仍然存在的地方

我尝试在线搜索许多网站，甚至测试了一些我自己的想法和一些来自 youtube 的想法，但 none 对我有用。
