这是我尝试运行页面时遇到的异常.我已经尝试根据我在网上看到的一些建议删除并重新创建bootstrap/cache.我已经尝试删除ServiceProvider文件中的参数以获取引导方法.什么都行不通.

我能猜到的最好的（我是 Laravel 的新手）是我的控制器返回 about.blade.php，它扩展了 layout.blade.php，但由于某种原因，layout.blade 甚至不知道 navbar.blade.php虽然 navbar.blade.php 扩展了 layout.blade.php。
layout.blade.php
<!DOCTYPE html>
<html>
<head>
</head>
<body>
@yield('navbar')
<div class="container">
@yield('content')
</div>
</body>
</html>
导航栏.blade.php
@extends('layout')
@section('navbar')
<header>
<nav class="nav navbar-default navbar-fixed-top">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle Navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="/?page=main">SWMHS</a>
</div>
<div class="collapse navbar-collapse" id="navbar-collapse-1">
<ul class="nav navbar-nav">
