composer install failure: no matching package found

Trying to install the module chosen with composer on D8.2 rc1

XXX:yyy zzz$ composer require drupal/chosen 2.0
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for drupal/chosen 2.0 -> satisfiable by drupal/chosen[2.0.0].
    - drupal/chosen 2.0.0 requires harvesthq/chosen ~1.5 -> no matching package found.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

Installation failed, reverting ./composer.json to its original content.
XXX:yyy zzz$

How to solve this? (I have tons of modules that install nicely, this one fails unfortunately). Thanks for the effort of diving into this.
