sudo composer install on Ubuntu

When I run the command:

sudo composer install

to deploy a new laravel 5.1 project, I get this error message:

Script php artisan clear-compiled handling the post-install-cmd event   returned with an error

I'm using Laravel's Envoyer to automatically deploy the project
Any Idea?
