Question

Solution 1

Most files are missing because you have not successfully installed Laravel.

Go to C:\xampp\htdocs\project> and type composer update --no-scripts or composer install

Since you are using xampp, once all the necessary files and packages are downloaded to your project you should be able to access your site through localhost without running php artisan serve by visiting

http://localhost/project/public

NB:Just ensure xampp is running

Solution 2

please go through the documentation first

https://laravel.com/docs/5.4#installation

you did not installed laravel projects correctly. you did not have vendor files. First you have to run :

composer install

dont need php artisan serve in xampp ... just go to

localhost/your_project/public

hope it helps !!!
