Laravel Tinker: класс «Psy \ Exception \ ErrorException» не найден

Я пытаюсь запустить Laravel 5.5, но получаю исключение, когда пытаюсь запустить заводскую Команду. Например:

factory(App\Article::class, 100)->create();

Когда я пытаюсь запустить, скажем, команда User: class в другом репозитории, она работает без проблем.

   PHP error:  Class 'Psy\Exception\ErrorException' not found in /Users/sebastian/Development/app.manager/vendor/psy/psysh/src/Psy/Shell.php on line 812

Что я пытался сделать:

• удаление и повторное добавление laravel / tinker из composer.json
