Pour installer une application:

on se positionne dans son dossier où l'on trouve 2 fichiers:

• composer.json
• composer.lock

$ composer install

# Sur DSM 6
$ composer.phar install

Si erreur, mettre à jour:

Warning: The lock file is not up to date with the latest changes in composer.json. You may be getting outdated dependencies. Run update to update them.
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for friendsofphp/php-cs-fixer v2.2.6 -> satisfiable by friendsofphp/php-cs-fixer[v2.2.6].
    - friendsofphp/php-cs-fixer v2.2.6 requires php ^5.3.6 || >=7.0 <7.2 -> your PHP version (7.2.3) does not satisfy that requirement.

Pour mettre à jour:

$ composer update
