===================================================================
Open your terminal using Ctrl+Alt+T
and type the following commands
composer global require "laravel/installer"
export PATH="~/.config/composer/vendor/bin:$PATH"
laravel new blog
cd blog
composer install
php artisan serve
Open a web browser and visit localhost:8000
to see the laravel welcome page
Terminate php server in terminal by pressing Ctrl+C
Thus you have successfully installed laravel globally.
I ran into the command
export PATH="~/.config/composer/vendor/bin:$PATH"
and that worked but, this command is to be run everytime to run laravel new blog globally.
please help
