Was excited to give flex a try until....
hbazzi$ composer create-project "symfony/skeleton:^3.3" links
[InvalidArgumentException]
Could not find package symfony/skeleton with version ^3.3 in a version installable using your PHP version 7.1.2.
Any news on when this will be available?
i have the same problem... how could you fix that?
Use a newer version of php
$ php -v
