How to install laravel 5.6 in a subdirectory? [closed]

I need to install laravel in a subfolder having the following structure. Route:

http://dominio/subcarpeta/

So I have the following folder structure:

private_part_of_laravel

public_html
|__parte_publica_de_laravel

and configure the index.php that is in:

public_html

|__ parte_publica_de_laravel
   |__ index.php

In the necessary lines:

require __DIR__.'/../../parte_privada_de_laravel/vendor/autoload.php';
$app = require_once __DIR__.'/../../parte_privada_de_laravel/bootstrap/app.php';

With this when when I make the request to:

GET http://dominio/parte_publica_de_laravel/

I am perfectly charged with the view of welcome.blade.php that is set in web.php

My problem starts when I issue the command:

php artisan make:auth

since when I enter the route:

GET http://dominio/parte_publica_de_laravel/login

sends me the view of a 404 error:

  

Sorry, the page you are looking for could not be found.

the same thing also happens when I try to define a new route:

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

If I enter the route

http://dominio/parte_publica_de_laravel/home

It also sends error 404:
