Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires provider/pkg * -> satisfiable by provider/pkg[1.0.0].
    - Only one of these can be installed: replacer/pkg 1.0.0, provider/pkg 1.0.0. They both provide third/pkg and can thus not coexist.
    - Root composer.json requires replacer/pkg * -> satisfiable by replacer/pkg[1.0.0].
