Target is not instantiable. Laravel 5 - App binding service provider - php

Question

I'm getting this error:
BindingResolutionException in compiled.php line 1029:
Target [App\Models\Contracts\Repositories\IUserRepository] is not instantiable.
My code is as follows:
Interface:
namespace App\Models\Contracts\Repositories;
use App\Models\Objects\DTO\User;
interface IUserRepository
{
function Create( User $user );
}
Concrete:
namespace App\Models\Concrete\Eloquent;
use App\Models\Contracts\Repositories\IUserRepository;
use App\Models\Objects\DTO\User;
class EqUserRepository implements IUserRepository
{
/**
* Create a new user instance after a valid registration.
*
* #param array $data
* #return User
*/
public function Create( User $user )
{
return User::create( [
'first_name' => $user->first_name,
'last_name' => $user->last_name,
'username' => $user->username,
'email' => $user->email,
'password' => bcrypt( $user->password ),
] );
}
}
Service Provider:
<?php namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider {
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
//
}
/**
* Register any application services.
*
* This service provider is a great spot to register your various container
* bindings with the application. As you can see, we are registering our
* "Registrar" implementation here. You can add your own bindings too!
*
* #return void
*/
public function register()
{
$this->app->bind(
'App\Models\Contracts\Repositories\IUserRepository',
'App\Models\Concrete\Eloquent\EqUserRepository'
);
}
}
Controller:
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use Illuminate\Contracts\Auth\Guard;
use Illuminate\Contracts\Auth\Registrar;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;
use App\Models\Contracts\Repositories\IUserRepository;
use App\Models\Objects\DTO\User;
class AuthController extends Controller
{
protected $auth;
private $userRepository;
public function __Construct(
Guard $auth,
IUserRepository $userRepo )
{
...
Folder structure
I have also seen that I may need to declare the namespaces in my composer.json, So i have tried the following as well as just the above:
"autoload": {
"classmap": [
"database"
],
"psr-4": {
"App\\": "app/",
"App\\Models\\Concrete\\Eloquent\\": "app/Models/Concrete/Eloquent/",
"App\\Models\\Contracts\\Repositories\\": "app/Models/Contracts/Repositories/",
"App\\Models\\Objects\\DTO\\": "app/Models/Objects/DTO/"
}
},
and then ran composer dump-autoload
Any ideas what I am forgetting to do?

Answer 1

I noticed the compiled.php was not being updated.
Run this function in cmd line on the root folder of your project:
php artisan clear-compiled

Answer 2

If you also run in below error :
BindingResolutionException in Container.php line 749: Target
[App\Contracts\TestContract] is not instantiable.
Clear your config cache with :
php artisan config:clear

Answer 3

I had same error solved by adding repository in app/providers/AppServiceProvider in register method like the below.
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
public function register()
{
$this->app->register(RepositoryServiceProvider::class); // here
}
}
