How to install the latest version of a package using composer in the command line?

Question

i'm trying to install the latest version of cviebrock/eloquent-sluggable that is compatible with laravel 5, i believe this is the 3.0.0-alpha / dev-master version. however when i run composer require cviebrock/eloquent-sluggable it try's to pull in version 2.x witch is only compatible with Laravel 4.

Using version ~2.0 for cviebrock/eloquent-sluggable
./composer.json has been updated

Installation failed, reverting ./composer.json to its original content.

i have also tried the following commands along with some others i came across while searching with no success.

composer require cviebrock/eloquent-sluggable --dev

composer require cviebrock/eloquent-sluggable --prefer-dist

iv been searching around to try and figure this out, but everything iv tried hasn't done the trick for me. Can someone point me in the right direction please? i'm still rather new at this.

Kind regards, Makka
