跳过作曲家PHP的要求

Question

We are using PHPCI and composer. The server which runs PHPCI is on PHP 5.3.

For a project we added the Facebook PHP SDK, using composer. It requires PHP 5.4. Composer gets triggered by PHPCI and get executed. But because the CI server just got PHP 5.3 composer failed with the error message:

facebook/php-sdk-v4 4.0.9 requires php >=5.4.0 -> no matching package found.

This let fail my build in PHPCI, of course.

Is there a possibility to skip this requirement? Maybe by adding an option to composer.json? Or a parameter to composer.phar call?

Answer 1

I've found the option:

composer install --ignore-platform-reqs

Ignore platform requirements (php & ext- packages).

Edit: You can skip the platform checks with this, but Composer will fetch packages based on given PHP version then. So when you need composer to also emulate a PHP version during depedency resolving, you can (and should!) use this in your composer.json:

{
    "config": {
       "platform": {
           "php": "5.6.6"
       }
    }
}
