Thread:Skin talk:Chameleon/Composer Installer Version/reply (2)

@Kaboomki: You seem to have specified a requirement for composer/installers version 1.0.12.0 specifically. You need to remove that requirement because mediawiki/chameleon needs composer/installers in any version >1.0.12.

@James: Setting minimum stability to dev should be enough. Chameleon's composer.json has a branch alias "dev-master": "1.x-dev".
