How to fix " Could not parse version constraint ^6.*: Invalid version string "^6.*"" - update composer

FYI - if you get an error message such as "Could not parse version constraint ^6.: Invalid version string "^6."" from composer, try updating composer:

composer self-update

(or see https://getcomposer.org/download/)
