after removing hirak/prestissimo, composer update is successable.
after change repositories.packagist packagist.org, error occurs, too.

error message:

Could you tell me your composer's version?
I guessed that you used stable version.

$ composer version

あと、日本語でも大丈夫です！

[watarukura]

$ composer --version
Composer version 1.0.0-alpha11 2015-11-14 16:21:07

↑でした。
$ composer --version
Composer version 1.0-dev (03299ff075236be27be356498d6c64def973fe41) 2016-01-10 20:34:53

updateした後はうまくいきました。
お騒がせいたしました。。。:bow:

さすがに最新のtaggedは動いて欲しいので調べてみますー

@watarukura 修正版を0.1.3としてリリースしました。アップデートしてみてください。alpha10まではこれで動きそうです。

$ composer global update hirak/prestissimo

確認遅くなってすみません。
正常に動きました！ありがとうございます。
