как устранить эту ошибку & quot; [ErrorException] count (): параметр должен быть массивом или объектом, который реализует Countable & quot ;?

[! [Я использую Windows 10 на моей машине. Я установил composer и затем laravel в корне документа, т.е. / var / www

Я также дал разрешение -R 777 на папку laravel, находящуюся в каталоге / var / www

Затем я захожу в каталог laravel с помощью cd / var / www / laravel и запускаю следующую команду php artisan, и я вижу там все доступные команды.

Затем я набрал в php artisan db: seed и получил ошибку]1]1
