Ошибка Symfony STDIN при установке через композитор

Я пытаюсь установить Symfony через композитор на Windows 7 с помощью команды

$ composer create-project symfony/framework-standard-edition www1

И я получаю ошибку

[ErrorException]
Use of undefined constant STDIN - assumed 'STDIN'

Что мне нужно сделать, чтобы решить эту проблему?

Также в полученном приложении было 3 пустых файла в папке «web / bundles», где должны быть папки пакетов с файлами css и изображениями. Из-за этого в браузере не было изображений на странице «web / app_dev.php». Затем я выполнил команду

php app/console assets:install web

и в «web / bundles» появились изображения и css-файлы, а затем изображения появились на странице «web / app_dev.php», поэтому они отображаются правильно.
