Requiring a package doesn't find a dependency When running HOME=/home/gymsagec composer require "drupal/commerce 8.2.x-dev", I get this error message:


  drupal/commerce 8.2.x-dev requires commerceguys/intl dev-master -> no matching package found


I can install the intl package by itself using composer but even after doing that, running the first script fails. Why?
As reported in Composer fails when installing a dependency of a dependency, but not when the dependency is installed directly. that probably happens because the root composer.json file doesn't set a minimum stability, or doesn't accept a less stable package.

Try with composer require drupal/commerce:@dev as suggested in that issue report.
