Почему не создается папка vendor в laravel?

Question

[lemonlimelike]

Установил laravel на реальный север этой командой

composer create-project --prefer-dist laravel/laravel blog

, прописал путь к файлу public/index.php, и захожу на сайт, а там ошибка

HTTP ERROR 500

, зашел в консоль и прописал команду:

tail -f /var/log/apache2/error.log

и вот что показало

Так понимаю, что папке vendor нету, ее и вправду нету, она не установилась почему-то, почему?
Выполнял команду composer update и вот что показывает:
и выполнил команду composer self-update,то пишет что такой команды нету.
