Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires pestphp/pest ^3.0 -> satisfiable by pestphp/pest[v3.0.0, ..., v3.7.1].
- pestphp/pest[v3.0.0, ..., v3.7.1] require php ^8.2.0 -> your php version (8.1.31) does not satisfy that requirement.
