Answer 1

Hier ist ein Tipp:

- phpunit/phpunit 4.0.0 requires symfony/yaml ~2.0 

Sie verwenden Symfony in der Version 3.0.*, die symfony/yaml Paket in der gleichen Version erfordert.

In der gleichen Zeit, die Sie PHPUnit in Version 4.0.* verwenden, die ~2.0symfony/yaml, aber in Version benötigt (was bedeutet,> = 2.0.0 und 3.0.0 <).

Sie haben also einen Konflikt hier.

Ich würde vorschlagen, PHPUnit-Paket 4.8-Version zu aktualisieren, die ~2.1|~3.0symfony/yaml in Version benötigt, die mit Symfony kompatibel ist 3.
