ReflectionException在Container.php第737行：

Question

我在试图显示我的网站时遇到了这个“堆栈跟踪”。我对此很陌生，但是这个错误看起来与laravel的系统文件有关。

这是我的route.php文件。 //（php打开标签）Route :: get（'/'，'HomeController @ index'）;

和我HomeController.php

<?php namespace App\Http\Controllers; 

use Illuminate\Routing\Controller; 

class HomeController extends Controller { 

public function index() 
    { 
      return view ('hello'); 
    } 

} 

这是我的看法文件hello.php

Answer 1

我对于某些身份验证问题获得了同样的问题。我通过以下两个步骤获得解决方案：

1. Put "league/oauth2-server": "4.1.*" on the require section of your composer.json file. 
2. run 'composer update' command on terminal. 

我希望它能帮助你。

Answer 2

更换use Illuminate\Routing\Controller;与use App\Http\Controllers\Controller;也做
