Composer installs symfony 3.4 instead of 4.x even with PHP 7.2

Question

I'm on Ubuntu 16.04.6 LTS + Plesk 17.8.11 with several PHP versions installed (7.0, 7.1 and 7.2) Even if I set the following line in the .bashrc file:

alias php='/opt/plesk/php/7.2/bin/php'

I check (with php -v) that the current PHP version actually is 7.2

BUT when I run the line :

composer create-project symfony/website-skeleton my-project

I still have Symfony 3.4 instead of 4.x

:(

Here is the the composer.json file after the "composer create-project symfony/website-skeleton myproject " command line:

Try composer create-project symfony/website-skeleton my-project 4.2 — Sindhara, Mar 09 '19 at 22:55
Maybe try installing composer again? Maybe composer was installed as a different user and somehow still has a path to an older php version? Seems unlikely. Just guessing. — Cerad, Mar 09 '19 at 23:40
Hi. If I use "composer create-project symfony/website-skeleton myproject 4.2" I get the error message : "[InvalidArgumentException] Could not find package symfony/website-skeleton with version 4.2." — Pulsar, Mar 10 '19 at 07:32

Here is the solution tat works for me : Since Composer will always use the default PHP version on the server, create an alias : alias composer='/opt/plesk/php/7.2/bin/php /usr/lib/plesk-9.0/composer.phar' and then Composer will install Symfony 4.x !

Composer installs symfony 3.4 instead of 4.x even with PHP 7.2
