After installing Composer it worked well, Laravel created all folders and it started correctly with:

php artisan serve

Now, when I try:

laravel new mypro

It does not create the vendor folder. And when I try:

php artisan serve

It says:

php artisan serve
PHP Warning:  require(/mnt/PROJECTS/[3]_PROCOM/[6]_PHP_Learning/Laravel_1/blog4/bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in /mnt/PROJECTS/[3]_PROCOM/[6]_PHP_Learning/Laravel_1/blog4/bootstrap/autoload.php on line 17
PHP Fatal error:  require(): Failed opening required '/mnt/PROJECTS/[3]_PROCOM/[6]_PHP_Learning/Laravel_1/blog4/bootstrap/../vendor/autoload.php' (include_path='.:/usr/share/php') in /mnt/PROJECTS/[3]_PROCOM/[6]_PHP_Learning/Laravel_1/blog4/bootstrap/autoload.php on line 17

After I copy folder vendor it says:

php artisan serve
PHP Fatal error:  Class 'Illuminate\Notifications\NotificationServiceProvider' not found in /mnt/PROJECTS/[3]_PROCOM/[6]_PHP_Learning/Laravel_1/blog3/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 146

I encountered the same problem. It occurred because the composer was not able to install the dependencies specified in composer.json file. try running

composer install

If this does not solve the problem, make sure the following PHP modules are installed php-mbstring php-dom

To install this extensions run the following in terminal

sudo apt-get install php-mbstring php-dom

once the installation is complete

try running the command again in your project root folder

composer install

So, if the above doesn't work, you can as well try this command

composer update --no-scripts

Instead of copying vendor folder please run a command

composer install

in your laravel's project directory

After trying multiple solutions from different sources, the only thing that worked for me was upgrading the PHP version.
