Kernel.php不存在Laravel 5

Question

我在学习laravel的同时学习了一个教程，但目前我遇到了这个错误

  

致命错误：未捕获ReflectionException：/var/www/html/cms/vendor/laravel/framework/src/Illuminate/Container/Container.php:734

中不存在类App \ Http \ Kernel

app / Http / Kernel.php中的类确实存在。

这些是文件的权限

-rw-rw-r-- 1 ivan www-data 1537 nov 26  2016 Kernel.php

这些是对整个目录文件的权限

-rw-rw-r--  1 ivan www-data    567 nov 26  2016 server.php

drwxr-xr-x 33 ivan www-data   4096 jun  2 15:48 vendor

当我在终端php artisan serve中运行并尝试在http://localhost:8000网站上加载网站时，该网站正在运行。

这里有什么问题？

Kernel.php

<?php

namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel
{
      ....

更新：来自console /

的Kernel.php

<?php

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;

class Kernel extends ConsoleKernel
{

更新：composer.json
