php - "Target [App\Http\Controllers\Controller] is not instantiable."

Question

我正在尝试按照关于 laravel 基础知识的 laracasts 教程进行操作，但是在毫无问题地安装了 composer 和 laravel 之后，我无法让我的路由文件与 Controller 一起工作仍然没有，有人看到这两个文件有什么问题吗？

routes.php 文件

<?php

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/

Route::get('/', 'Controller@index');
Route::get('contact', 'Controller@contact');

controller.php文件

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;

abstract class Controller extends BaseController
{
    use DispatchesJobs, ValidatesRequests;

    public function ___construct()
    {
        $this->middleware('guest');
    }

    public function index()
    {
        return 'hello world!';
    }

    public function contact()
    {
     return 'Contact me!';
    }
}

如果有任何帮助，我使用 phps 服务器命令将它托管在 localhost:8888 上。

原因可能是您的 Controller 类是抽象的，因此它不可实例化。删除抽象关键字。
