Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require htmlmin/htmlmin:*" to figure out if any version is installable, or "composer require htmlmin/htmlmin:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.`
