无法使用作曲家设置奏鸣曲

Question

我用作曲家建立了交响乐。

我在composer.json文件中添加了一些依赖项，如下所示：

{
"name": "symfony/framework-standard-edition",
"license": "MIT",
"type": "project",
"description": "The \"Symfony Standard Edition\" distribution",
"autoload": {
    "psr-0": { "": "src/" }
},
"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.3.*",
    "doctrine/orm": ">=2.2.3,<2.4-dev",
    "doctrine/doctrine-bundle": "1.2.*",
    "twig/extensions": "1.0.*",
    "symfony/assetic-bundle": "2.3.*",
    "symfony/swiftmailer-bundle": "2.3.*",
    "symfony/monolog-bundle": "2.3.*",
    "sensio/distribution-bundle": "2.3.*",
    "sensio/framework-extra-bundle": "2.3.*",
    "sensio/generator-bundle": "2.3.*",
    "incenteev/composer-parameter-handler": "2.0",
    "sonata-project/admin-bundle": "dev-master",
    "sonata-project/doctrine-orm-admin-bundle": "dev-master",
    "sonata-project/intl-bundle": "dev-master",
    "sonata-project/user-bundle": "dev-master"
},
"scripts": {
    "post-install-cmd": [
        "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile"
    ],
    "post-update-cmd": [
        "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile"
    ]
},
"config": {
    "bin-dir": "bin"
},
"minimum-stability": "stable",
"extra": {
    "symfony-app-dir": "app",
    "symfony-web-dir": "web",
    "incenteev-parameters": {
        "file": "app/config/parameters.yml"
    },
    "branch-alias": {
        "dev-master": "2.3-dev"
    }
}
}

当我运行composer.phar更新时，我收到以下消息：

用包信息加载作曲家存储库更新依赖项（包括要求开发）您的需求无法解析为一组可安装的包。

问题1-索纳塔项目/intl捆绑包开发主机的安装html" target="_blank">请求-

因此，我不知道还有什么更好的方法，我想我可能需要运行composr.phar安装，这给了我以下信息：

加载带有包信息的作曲家存储库从锁文件安装依赖项（包括要求开发）警告：锁文件不是最新的composer.json.您可能会得到过时的依赖项。运行更新以更新它们。您的需求无法解析为一组可安装的包。

问题1-symfony/framework标准版2.3.x-dev的安装请求-

潜在原因：-软件包名称输入错误-根据最低稳定性设置，软件包的版本不够稳定，请参阅https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion 更多细节。

阅读http://getcomposer.org/doc/articles/troubleshooting.md 了解更多常见问题。

我已经按照sonata-project.org的指示进行了操作，但没有取得任何进展。

我是不是犯了什么明显的错误？

下面是一个有效的composer.json，用于使用symfony 2.3设置sonata管理员*

"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.3.*",
    "doctrine/orm": ">=2.2.3,<2.4-dev",
    "doctrine/doctrine-bundle": "1.2.*",
    "twig/extensions": "1.0.*",
    "symfony/assetic-bundle": "2.3.*",
    "symfony/swiftmailer-bundle": "2.3.*",
    "symfony/monolog-bundle": "2.3.*",
    "sensio/distribution-bundle": "2.3.*",
    "sensio/framework-extra-bundle": "2.3.*",
    "sensio/generator-bundle": "2.3.*",
    "incenteev/composer-parameter-handler": "~2.0",
    "twig/twig": "1.*",
    "knplabs/knp-menu-bundle" : "1.1.*",
    "sonata-project/block-bundle" : "dev-master",
    "sonata-project/exporter" : "1.1.0",
    "sonata-project/jquery-bundle" : "1.8.*",
    "sonata-project/cache-bundle" : "dev-master",
    "sonata-project/intl-bundle" : "dev-master",
    "sonata-project/admin-bundle" : "dev-master",
    "sonata-project/doctrine-orm-admin-bundle" : "dev-master",
},

您还必须安装INTL扩展：http://php.net/manual/en/intl.setup.php
