无法通过 composer require 获取包

Question

I want to user this package hslavich/simplesamlphp-bundle in my project which has dependency on simplesamlphp/simplesamlphp dev-master

If I try to add dependency like this:

composer require hslavich/simplesamlphp-bundle dev-master

I get the following error:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for hslavich/simplesamlphp-bundle dev-master -> satisfiable by hslavich/simplesamlphp-bundle[dev-master].
    - hslavich/simplesamlphp-bundle dev-master requires simplesamlphp/simplesamlphp dev-master -> no matching package found.

If I git clone the hslavich/SimplesamlphpBundle and use composer update simplesamlphp package is downloaded successfully.

What am I doing wrong?

Add "minimum-stability": "dev" to composer.json. The usage of dev package versions imples that you need to have it. Use

"minimum-stability": "dev",
"prefer-stable" : true

if you don't want it to affect other packages without strict version constraints.
