Для Semantic MediaWiki требуется onoi / callback-контейнер, но его нельзя установить

Я пытаюсь установить последнюю версию SemanticMediaWiki. Когда я бегу composer update, он возвращает следующее:

> ComposerHookHandler::onPreUpdate

Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - mediawiki/semantic-media-wiki 2.4.x-dev requires onoi/callback-container ~1.0 -> satisfiable by onoi/callback-container[1.0.0, 1.1.0] but these conflict with your requirements or minimum-stability.
    - mediawiki/semantic-media-wiki 2.4.6 requires onoi/callback-container ~1.0 -> satisfiable by onoi/callback-container[1.0.0, 1.1.0] but these conflict with your requirements or minimum-stability.
    - mediawiki/semantic-media-wiki 2.4.5 requires onoi/callback-container ~1.0 -> satisfiable by onoi/callback-container[1.0.0, 1.1.0] but these conflict with your requirements or minimum-stability.

    - mediawiki/semantic-media-wiki 2.4.1 requires onoi/callback-container ~1.0 -> satisfiable by onoi/callback-container[1.0.0, 1.1.0] but these conflict with your requirements or minimum-stability.
    - Installation request for mediawiki/semantic-media-wiki ~2.4.1 -> satisfiable by mediawiki/semantic-media-wiki[2.4.1, 2.4.2, 2.4.3, 2.4.4, 2.4.5, 2.4.6, 2.4.x-dev].

Я даже установил minimum-stability к dev и даже prefer-stable к false. Ничего не разрешается.

Это не первая проблема с Composer. Он возвратил ошибку из-за отсутствия набора version в пакете mediawiki/core, что требовалось еще для этого SMW. Но не сейчас, сюрприз.

И Composer не видит пакет в composer show onoi/callback-container. Есть вообще стабильная версия 2.0.
