When calling cpx stolt/lean-package-validator validate I get the following error message:

Runtime environment

$ cpx --version
cpx version: 1.0.1
php version: 8.2.21

$ composer2 --version
Composer version 2.7.9 2024-09-04 14:43:28
PHP version 8.2.21 (/usr/bin/php8.2)

Currently cpx is using the global composer command loaded in your shell. Since I see you're running composer2 here, is composer --version running the (now deprecated) v1?

I can aim to make cpx smarter about finding the correct Composer install (or give a better error message in this scenario if it only finds v1).

For what it's worth, this command seems to run perfectly fine for me:

cpx stolt/lean-package-validator validate

stolt/lean-package-validator is already installed and doesn't need updating.
