Class App\Repositories\UserRepository does not exist

<?php

namespace App\Http\Controllers;


use Illuminate\Contracts\Auth\Guard;
use Laravel\Socialite\Contracts\Factory as Socialite; 
use App\Repositories\UserRepository;


class SocialController extends Controller
{
    /**
     * Redirect the user to the GitHub authentication page.
     *
     * @return Response
     */

    private $socialite;
     private $auth;
     private $users;

     public function __construct(Socialite $socialite, Guard $auth, UserRepository $users) {   
        $this->socialite = $socialite;
        $this->users = $users;
        $this->auth = $auth;
    }
}

This is my controller. While I'm loading this controller it showing an error like

"ReflectionException in Container.php line 791: Class App\Repositories\UserRepository does not exist".

Can anyone suggest me a solution?
