404：找不到文件。 Laravel无法加载home.blade.php文件

I'm new to the Laravel framework, so I'm following this tutorial, cloning instagram. After designing the front end, all was going well, until I started working with php artisan. I have created the user and profile database, migrated them successfully, and linked them in a one-to-one relationship.

But, after this, trying to login, and navigate to home, I'm getting a

404, not found error

I can't seem to figure out what's wrong.

profileController:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class profilesController extends Controller
{
     public function index($user)
    {
        $user = \App\User::find($user);
        return view('home', [
            'user' => $user,
        ]);
    }
}

homeController:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class HomeController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Contracts\Support\Renderable
     */       
}

web.php:

  Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/profile/{user}', 'profilesController@index')->name('profile.show');

profile created via php artisan

$profile->user
=> App\User {#2975
     id: "1",
     name: "Sofolahan Eniola Ademola",
     email: "princeademola85@gmail.com",
     username: "usertesst",
     email_verified_at: null,
     created_at: "2019-07-27 16:01:45",
     updated_at: "2019-07-27 16:01:45",
   }
>>> $profile
=> App\profile {#2965
     title: "cool stuff",
     description: "desc stuff",
     user_id: 1,
     updated_at: "2019-07-27 16:04:45",
     created_at: "2019-07-27 16:04:45",
     id: 1,
     user: App\User {#2975
       id: "1",
       name: "Sofolahan Eniola Ademola",
       email: "princeademola85@gmail.com",
       username: "usertesst",
       email_verified_at: null,
       created_at: "2019-07-27 16:01:45",
       updated_at: "2019-07-27 16:01:45",
     },
   }

Am I missing something?
