我尝试安装SemanticMediaWiki的最新版本。 当我运行composer update ，它返回以下内容：
> ComposerHookHandler::onPreUpdate Loading composer repositories with package information 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 2.4.4 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 2.4.3 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 2.4.2 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].
我甚至设定了开发的minimum-stability ，甚至prefer-stable到false 。 没有任何结果。
这不是Composer的第一个问题。 它由于mediawiki/core软件包中没有设置version而返回了一个错误，这仍然是由SMW所要求的。 但是在这个时候还不是很惊讶。
Composer在composer show onoi/callback-container不到该包。 有稳定的2.0版本。
