我正在尝试安装symfony 2.2。*但它显示此错误
"require": {
"php": ">=5.3.3",
"symfony/symfony": "2.2.*",
"sonata-project/admin-bundle": "2.3.*@dev",
"sonata-project/cache-bundle": "dev-master",
"sonata-project/block-bundle": "2.2.*@dev",
"sonata-project/jquery-bundle": "1.10.*@dev",
"sonata-project/doctrine-orm-admin-bundle" : "2.3.*@dev",
"sonata-project/core-bundle": "2.2.*",
"doctrine/orm": "~2.2,>=2.2.3",
"doctrine/doctrine-bundle": "1.2.*",
"twig/extensions": "1.0.*",
"symfony/assetic-bundle": "2.1.*",
"symfony/swiftmailer-bundle": "2.2.*",
"symfony/monolog-bundle": "2.2.*",
"sensio/distribution-bundle": "2.2.*",
"sensio/framework-extra-bundle": "2.2.*",
"sensio/generator-bundle": "2.3.*@dev",
这是出现的错误。 我猜它会按顺序检查每个版本，但最后它不会安装任何版本。
我已多次更改版本，但它已经解决了。

Symfony2.2。*不再支持。 http://symfony.com/roadmap?version=2.2
尝试更改版本说明或按照说明进行操作

你的问题来自奏鸣曲库。您尝试安装"sonata-project/admin-bundle": "2.3.*@dev"，而此版本仅根据packagist与Symfony＆gt; = 2.3兼容。其他奏鸣曲库也是如此。
所以，你有两个解决方案：
基本上，在需要库之前，如果您指定的版本与其他软件包兼容，则需要检查http://packagist.org。
