PHP Fatal error:Uncaught Error: Failed opening required 'new-project/vendor/autoload.php' (include_path='.;C:\php\pear') in E:\new-project\artisan:18

Question

I want to create new laravel project by composer. I use composer create-project laravel/laravel new-project command for create new project. then, my project is created following this picture.

I start Laravel's local development server using the Laravel's Artisan CLI serve command (first cd new-project and then php artisan serve command). But I got the following error.

Why is there no vendor folder in this project?!!!
How do I fix this error?

(I used PHP 8.1.10)

Maybe change the phrasing in the title. It reads like you're asking how to prevent it from being created while the question asks why it wasn't. Did you get any errors or anything when you ran composer create-project laravel/laravel new-project? — M. Eriksson

You need to issue composer install to install packages which creates the vendor/ folder

You need to delete the vendor folder if you already have one in your project, and run composer install. Then restart your server.
