    Your requirements could not be resolved to an installable set of packages.

      Problem 1
        - symfony/thanks v1.0.1 requires composer-plugin-api ^1.1 -> no matching package found.
        - symfony/thanks v1.0.0 requires composer-plugin-api ^1.1 -> no matching package found.
        - Installation request for symfony/thanks ^1.0 -> satisfiable by symfony/thanks[v1.0.0, v1.0.1].

    Potential causes:
     - A typo in the package name
     - The package is not available in a stable-enough version according to your minimum-stability setting
       see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.

Remove your composer cache first. run composer clearcache and composer self-update
