Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires nuwave/lighthouse * -> satisfiable by nuwave/lighthouse[v0.1.0, ..., v0.7.8, v1.0.0, ..., v1.1.0, v2.0.0, ..., v2.6.4, v3.0.0, ..., v3.7.0, v4.0.0, ..., v4.18.0, v5.0.0, ..., v5.72.0, v6.0.0, ..., v6.50.0].

You can also try re-running composer require with an explicit version constraint, e.g. "composer require nuwave/lighthouse:*" to figure out if any version is installable, or "composer require nuwave/lighthouse:^2.1" if you know which you need. ...............................................................................................................................................................................................................then my composer.json file {
