Your requirements could not be resolved to an installable set of packages.
Problem 1
kreait/firebase-php[6.0.0, ..., 6.x-dev] require lcobucci/jwt ^4.1 -> found lcobucci/jwt[4.1.0, ..., 4.2.x-dev] but the package is fixed to 3.2.5 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
Root composer.json requires kreait/laravel-firebase ^4.1 -> satisfiable by kreait/laravel-firebase[4.1.0].
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 kreait/laravel-firebase:*" to figure out if any version is installable, or "composer require kreait/laravel-firebase:^2.1" if you know which you need.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
