Laravel 5.3 - InvalidArgumentException View [index] not found [duplicate]

I already deployed my Laravel app into my VPS. It works fine on localhost. I think the error is in my routes or maybe the controller because the path is still going into my local machine directory (see error message line 2) but I really can't see the problem in the code.

I have tried using php artisan config:cache, php artisan cache:clear, php artisan route:cache but it still doesn't work. It still refers to my local machine directory.

This is the directory of index.blade.php

Root
|-- portofolio
    |-- app
    |-- bootstrap
    |-- config
    |-- database
    |-- resources
        |-- assets
        |-- lang
        |-- views
            |-- index.blade.php
    |-- routes
    |-- storage
    |-- tests
    |-- vendor
|-- public_html
    |-- css
    |-- img
    |-- js
    |-- vendor

This is the Route

Route::get('/', ['as' => 'home', 'uses' => 'Portofolio@link']);

This is the Controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class Portofolio extends Controller
{
public function link() {

    $categories = [
        '1' => 'Print Design',
        '2' => 'Logo Design',
        '3' => 'Web Design',
        '4' => 'Product Design',
        '5' => 'Character Design',
        '6' => 'Packaging Design'
    ];

    $projects = [
        '1' => 'IMSAA Training Certificate',
        '2' => 'Rusticity Logo',
        '3' => 'Handy Production Website',
        '4' => 'Nihon no Matsuri Bag Project',
        '5' => 'The Chin - Captain Jack Sparrow',
        '6' => 'Rusticity Packaging'
    ];

    $images = [
        '1' => '1',
        '2' => '2',
        '3' => '3',
        '4' => '4',
        '5' => '5',
        '6' => '6'
    ];

    $skills = [
        '1' => 'Photoshop',
        '2' => 'Ms. Office',
        '3' => 'Laravel',
        '4' => 'PHP',
        '5' => 'HTML',
        '6' => 'MySQL'
    ];

    $points = [
        '1' => '80%',
        '2' => '90%',
        '3' => '60%',
        '4' => '60%',
        '5' => '60%',
        '6' => '60%'
    ];

    return view('index')->withCategories($categories)->withProjects($projects)->withImages($images)->withSkills($skills)->withPoints($points);
}
}

This is the error message (see line 2)
