drush/drush[12.0.0, ..., 12.2.0] require composer-runtime-api ^2.2

Resources - changing Drush

Updating Drush went OK on all testing environments until on to the staging environment. 

The initial error that I saw was

PHP Fatal error:  Declaration of Drush\Style\DrushStyle::confirm($question, $default = true) must be compatible with Symfony\Component\Console\Style\SymfonyStyle::confirm(string $question, bool $default = true): bool in /var/www/html/{project}/vendor/drush/drush/src/Style/DrushStyle.php on line 11

Followed by attempting to run composer update

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

  Problem 1
    - drush/drush[12.0.0, ..., 12.2.0] require composer-runtime-api ^2.2 -> found composer-runtime-api[2.1.0] but it does not match the constraint.
    - Root composer.json requires drush/drush ^12 -> satisfiable by drush/drush[12.0.0, ..., 12.2.0].

To resolve this problem, update your composer by running the following command:

composer self-update
