Php &引用；symfony框架标准版“；需要旧版本

我正在尝试安装

“symfony/框架标准版”：“2.6.6”

然而

php composer.phar更新

显示此错误

  Problem 1
    - Installation request for symfony/framework-standard-edition 2.2.x-dev -> satisfiable by symfony/framework-standard-edition[2.2.x-dev].
    - Can only install one of: symfony/framework-standard-edition[v2.6.6, 2.2.x-dev].
    - Installation request for symfony/framework-standard-edition 2.6.6 -> satisfiable by symfony/framework-standard-edition[v2.6.6].

为什么symfony framework标准版[2.6.6]需要标准版[2.2.x]

这是我的composer.json
