Почему не ставится ratchet?

Question

[exxagw]

Поставил composer (socketo.me/docs/install)
создаю composer.json по гайду
пишу в консоле

php /var/www/web/data/www/**** domain *****/composer.phar install

выдает ошибку:

Loading composer repositories with package information
Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - cboden/ratchet v0.3.2 requires php >=5.3.9 -> no matching package found.
    - cboden/ratchet v0.3.1 requires php >=5.3.9 -> no matching package found.
    - cboden/ratchet v0.3.0 requires php >=5.3.9 -> no matching package found.
    - Installation request for cboden/ratchet 0.3.* -> satisfiable by cboden/ratchet[v0.3.0, v0.3.1, v0.3.2].

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
