[SOLVED]artisan clear-compiled return error code 255

When runnning composer install on my laravel project I get the error:

Script php artisan clear-compiled handling the post-install-cmd event returned with error code 255

Any advice on what could be the issue? Note composer installs all the vendor packages. The full output is below:

[user@some_path]$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files
> php artisan clear-compiled
Script php artisan clear-compiled handling the post-update-cmd event returned with error code 255
