I get the following error:
PHP Fatal error: Declaration of Symfony\Flex\Command\RequireCommand::execute(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output) must be compatible with Composer\Command\RequireCommand::execute(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output): int in /var/www/html/vendor/symfony/flex/src/Command/RequireCommand.php on line 44
