Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/cache ^4.3, found symfony/cache[v4.3.0, ..., v4.4.48] but these were not loaded, because they are affected by security advisories ("PKSA-z7t6-zt6p-wtng", "PKSA-w17b-j6zx-knvn"). Go to https://packagist.org/security-advisories/ to find advisory details. To ignore the advisories, add their IDs to the "policy.advisories.ignore-id" config or add the package to "policy.advisories.ignore". To turn the feature off entirely, you can set "policy.advisories.block" to false.
