Your requirements could not be resolved to an installable set of packages. Problem 1 - nanbando/mysql[0.4.1, ..., 0.4.2] require symfony/process ^5.2 -> satisfiable by symfony/process[v5.2.0, ..., v5.4.40] from composer repo (https://repo.packagist.org) but symfony/process[v7.1.1] from installed array repo (defining 93 packages) has higher repository priority. The packages from the higher priority repository do not match your constraint and are therefore not installable. That repository is canonical so the lower priority repo's packages are not installable. See https://getcomposer.org/repoprio for details and assistance. - nanbando/mysql 0.4.3 requires symfony/process ^5.2 || ^6.0 -> satisfiable by symfony/process[v5.2.0, ..., v5.4.40, v6.0.0, ..., v6.4.8] from composer repo (https://repo.packagist.org) but symfony/process[v7.1.1] from installed array repo (defining 93 packages) has higher repository priority. The packages from the higher priority repository do not match your constraint and are therefore not installable. That repository is canonical so the lower priority repo's packages are not installable. See https://getcomposer.org/repoprio for details and assistance. - Root composer.json requires nanbando/mysql ^0.4.1 -> satisfiable by nanbando/mysql[0.4.1, 0.4.2, 0.4.3].
