Bug #83330

TYPO3 8.7.9 depends on "symfony/yaml" which requires PHP 7.1, but the official system requirements state only PHP 7.0
0%
Description
After upgrading one of our v8 installations running on PHP 7.0 to version 8.7.9 it started throwing exceptions about nullable return values (the question mark flag to allow null returns) in the Symfony yaml parser. The composer dependencies of symfony/yaml state "^7.1.3" for PHP - so the latest TYPO3 core update actually raised the minimum PHP version implicitly to 7.1, even though 7.0 is the official requirement.
This could bring a lot of installations down when they update.

are you maybe updating your site while having PHP 7.1 locally available? then you will get different packages then using 7.0

You are right, we used PHP 7.1 on the composer update, but had PHP 7.0 on the live system. Updating with PHP 7.0 fixed it.
But apparently it does not matter if TYPO3 has the "high" or the "low" Symfony package version. So, to me it still seems wrong (but less fatal now) to install package versions that are probably incompatible on another system that actually meets the official requirements.

The PHP version is a requirement which is checked during a composer install/update and you will get those packages which fits best for you. However using the same PHP version for building as in production is something you need to care yourself. I am closing this issue therefore.
