解决未捕获的ReflectionException：C：\ ... \ Container.php中不存在类日志：

Question

我遇到了class log does not exist意外的反射异常错误。我目前正在使用Laravel 5.2。在命名空间中使用log添加到我的控制器中并没有解决这个问题。

Fatal error: Uncaught ReflectionException: Class log does not exist in C:\xampp\htdocs\laravel\vendor\laravel\framework\src\Illuminate\Container\Container.php:741

Controller.php这样

  <?php

namespace App\Http\Controllers;

use Log;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesResources;
use Illuminate\Database\Eloquent\ModelNotFoundException;

 class Controller extends BaseController
{
    use AuthorizesRequests,AuthorizesResources, DispatchesJobs, ValidatesRequests;
}

routes.php文件

<?php

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
Route::get('/', function () {
    return view('welcome');
});

按照此处的建议检查.env或配置文件中的空格

用双引号括起来（如果有的话）
