解决方案

您已经安装了 bootstrap 4 并使用了 bootstrap 3 版本的导航栏代码.这里是 bootstrap 4 导航栏的示例代码.在最新的 bootstrap 4 版本中，某些类已更改.

<ul class="navbar-nav"><li class="nav-item"><a class="nav-link" href="#">链接 1</a><li class="nav-item"><a class="nav-link" href="#">链接 2</a><li class="nav-item"><a class="nav-link" href="#">链接 3</a></nav>
