composer.json是： http://pastebin.centos.org/119096/

Answer 1

这里有一个提示：

- phpunit/phpunit 4.0.0 requires symfony/yaml ~2.0

您在版本3.0.*中使用Symfony，在同一版本中需要symfony/yaml个包。

同时您在版本4.0.*中使用PHPUnit，但需要symfony/yaml，但版本为~2.0（这意味着＆gt; = 2.0.0和<3.0} 0.0）。

所以你在这里发生冲突。

我建议将PHPUnit软件包更新为4.8版本，版本symfony/yaml需要~2.1|~3.0，与Symfony 3兼容。
