Question

I'm getting a flood of messages when I run 'composer.phar update' on my Centos 6.4 / PHP 5.5.36 server starting with:

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of 
packages.

Answer 1

Here's a hint:

- phpunit/phpunit 4.0.0 requires symfony/yaml ~2.0 

You're using Symfony in version 3.0.* , which requires symfony/yaml package in the same version.

In the same time you're using PHPUnit in version 4.0.* which requires symfony/yaml , but in version ~2.0 (which means >=2.0.0 and <3.0.0).

So you have a conflict here.

I would suggest to update PHPUnit package to 4.8 version, which requires symfony/yaml in version ~2.1|~3.0 , which is compatible with Symfony 3.
