目標[App \ Http \ Controllers \ IndexController]不可實例化。在laravel

我已經從github克隆項目，並安裝在我的本地系統一切工作正常。目標[App Http Controllers IndexController]不可實例化。在laravel

而我通過命令創建了控制器，控制器已創建，但是當我嘗試使用控制器功能時，該錯誤如下所示。

BindingResolutionException

目標[應用\ HTTP \控制器\ SomeController]不是實例化。在Container.php（線895）

我試圖通過運行下面的命令來解決這個問題：

PHP人員緩存：清楚

PHP人員清楚編譯

composer dump-autoload

php artisan optimize

php artisan config：clear

但我仍然有同樣的錯誤。請幫我解決這個問題。

我的控制器：

<?php 

namespace App\Http\Controllers; 

use Illuminate\Http\Request; 

class SomeController extends Controller 
{ 
    public function getIndex() { 
    echo "string"; 
    } 
}

AppServiceProvider.php：

<?php 

namespace App\Providers; 

use Illuminate\Support\ServiceProvider; 
use Illuminate\Support\Facades\Schema; 

class AppServiceProvider extends ServiceProvider 
{ 
/** 
* Bootstrap any application services. 
* 
* @return void 
*/ 
public function boot() 
{ 
    // 
    Schema::defaultStringLength(191); 
} 

    /** 
    * Register any application services. 
    * 
    * @return void 
    */ 
    public function register() 
    { 
     // 
    } 
}

Controller.php這樣

<?php 

namespace App\Http\Controllers; 

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

    return 0;*/ 
} 

public function getDownload($file_path,$file_name)

提供您的'AppServiceProvider.php'代碼來檢查你的代碼，隨後 –

已經更新了我的問題與appserviceprovider通過使你的父母控制器的構造函數，而不是公衆的保護 – Vinothini

嘗試結合的方式@ V.php：你正在使用哪個laravel版本？ –

更新您的SomeController與下面的代碼：

<?php 

namespace App\Http\Controllers; 
use App\Http\Controllers\Controller; 
use Illuminate\Http\Request; 

class SomeController extends Controller 
{ 
    public function getIndex() { 
     echo "string"; 
    } 
}

希望爲你工作！
