Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires squizlabs/php_codesniffer ^2.3, found squizlabs/php_codesniffer[2.3.0, ..., 2.9.2] but these were not loaded, because they are affected by security advisories ("PKSA-rdkp-vv9z-mjkg", "PKSA-6vdd-n4sx-knhy"). 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.
