Laravel installer has been install but laravel command not found ... wtf? : I've got an issue with trying tu use laravel installer.

I follow each steps to install laravel installer globally from https://laravel.com/docs/6.x,

 - sudo composer global require laravel/installer
 - export PATH="/home/hedwin/.composer/vendor/bin:$PATH"

But laravel command isn't found in sudo, but it's found with error without sudo ...
