Error while running php artisan serve command on localhost

Question

I am having issues with php artisan serve command. I am working on one Laravel project and when I access the folder from browser it is working fine but when I run the php artisan serve command it shows me the following error:

Warning: require(E:\\xampp\\htdocs\\www\\LFS\\public../vendor/autoload.php): failed to open stream: No such file or directory in E:\\xampp\\htdocs\\www\\LFS\\public\\index.php on line 24

Fatal error: require(): Failed opening required 'E:\\xampp\\htdocs\\www\\LFS\\public../vendor/autoload.php' (include_path='E:\\xampp\\php\\PEAR') in E:\\xampp\\htdocs\\www\\LFS\\public\\index.php on line 24

I am new to Laravel please let me know where I am going wrong.

I have checked the code in the public/index.php file below is my code. I guess everything is fine I just copy-paste the same index.php file on my root folder.

<?php

/**
 * Laravel - A PHP Framework For Web Artisans
 *
 * @package  Laravel
 * @author   Taylor Otwell <taylor@laravel.com>
 */

define('LARAVEL_START', microtime(true));

/*

|
*/

require __DIR__.'../vendor/autoload.php';

/*

| the responses back to the browser and delight our users.
|
*/

$app = require_once __DIR__.'../bootstrap/app.php';

/*

| Run The Application
|--------------------------------------------------------------------------
|
| Once we have the application, we can handle the incoming request
| through the kernel, and send the associated response back to
| the client's browser allowing them to enjoy the creative
| and wonderful application we have prepared for them.
|
*/

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

$response->send();

$kernel->terminate($request, $response);

I want that the project can be directly accessible from the browser and should also run on the php artisan serve command.

Answer 1

In your project folder, the vendor folder is missing so you got this error:

Warning: require(E:\\xampp\\htdocs\\www\\LFS\\public../vendor/autoload.php): failed to open stream: No such file or directory

Just run this command:

composer update --no-scripts 
composer update

With this command, you will re-create the vendor folder in your project
