Вызов неопределенного метода [пакет]

Я пытаюсь написать плагин, в папке с плагином создан composer.json

{
"Require": {
"Php": "> = 5.4.0",
"Mattbrown / laracurl": "2.0.0"}
}

положить plugin.php

public function boot ()
{
App :: register ('\ Mattbrown \ Laracurl \ LaracurlServiceProvider');
}

Но при звонке на любую страницу происходит следующий перехват

Call to undefined method [package]
***** / Vendor / laravel / framework / src / Illuminate / Support /    ServiceProvider.php line 226
