Upgrade fxp/composer-asset-plugin to latest version (1.2.1) and composer to latest version (1.2.0).

composer global require "fxp/composer-asset-plugin:^1.2.0"
composer selfupdate

Try `composer selfupdate` first. If it's not working remove the fxp plugin then update composer and then add fxp again. – Bizley Aug 05 '16 at 08:43

Thank you all for your advising! Compouser didn't accept any command the problem above had appear always. I think the problem appear after that i had change php.ini file. Problem solved by reinstaling Compouser and Xampp
