I try to install the latest release of SemanticMediaWiki. When I run composer update, it returns the following:

> 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].

I have even set minimum-stability to dev and even prefer-stable to false. Nothing resolves.

It is not the first problem with Composer. It returned an error due to no set version in package mediawiki/core, which was required still by this SMW. But not at this time, surprise.

And Composer don't see the package in composer show onoi/callback-container. There is stable version 2.0 at all.

Double check your composer.json and how you're requiring the version, this file worked for me:

{
  "require-dev": {
    "mediawiki/semantic-media-wiki": "~2.4.1"
  }
}

which is equivalent to composer require mediawiki/semantic-media-wiki:~2.4.1 command.

If composer show doesn't see the right package, try the following commands:

  • composer clean to clear the caches.
  • composer diagnose to check for common errors.
