the issue is because I want to add Zend\I18n\Validator\IsInt, but no package found, works after added. But I think the error should be more verbose to user.

Oh, so to be sure, the issue concerns directly the error message.

Good thinking, please make a commit that would make sense to this issue and let us review it.

( I love verbose)

;)
