I don't have a problem with zip as regards to the link. My error is different from that of the link. — Victor Anuebunwa, Jul 21 '18 at 11:41

composer cannot find some commit from git cache, so order it to get package directly from its repository. this works for me:

composer install --prefer-dist

(sudo) yum install zip unzip php-zip

or
