how can i solved it
Install php 7.1 and you will be fine.
For ubuntu https://www.vultr.com/docs/how-to-install-and-configure-php-70-or-php-71-on-ubuntu-16-04
For windows http://php.net/manual/en/install.windows.php
You have to update your php version to be 7, after that you have to re install your composer and make sure that it will take correct php version
