Answer 1

Try to run from command line

composer install 
or composer update

Answer 2

You just need to run composer update to update your dependencies as they are specified in this file: composer.json . The command will generate vendor/autoload.php , too.

Laravel utilizes Composer to manage its dependencies. First, download a copy of the composer.phar . Once you have the PHAR archive, you can either keep it in your local project directory or move to usr/local/bin to use it globally on your system.

On Windows, you can use the Composer Windows installer .
