Symfony作曲家更新“冻结”更新依赖项

使用Symfony2，将nelmio / api-doc-bundle添加到我的composer.json中。我的档案就像

{
"name": "symfony/framework-standard-edition",
"license": "MIT",
"type": "project",
"description": "The \"Symfony Standard Edition\" distribution",

    "coresphere/console-bundle": "dev-master",
    "nelmio/api-doc-bundle": "2.4.5"
},
"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"
},
"extra": {
    "symfony-app-dir": "app",
    "symfony-web-dir": "web",
    "incenteev-parameters": {
        "file": "app/config/parameters.yml"
    },
    "branch-alias": {
        "dev-master": "2.4-dev"
    }
}

}

但是，当我运行composer update时，脚本会阻止更新依赖项。详细地说，这是冻结的行：

Reading /root/.composer/cache/repo/https---packagist.org/provider-jms$cg.json from cache

在添加nelmio / api-doc-bundle之前还不错，但是我在另一个捆绑包中也遇到了同样的问题（最终我重置了项目）。

编辑02/07：当我执行作曲家安装（使用--prefer-dist或--prefer-source）时，出现以下错误：

Your requirements could not be resolved to an installable set of packages.



Problem 1
    - The requested package friendsofsymfony/rest-bundle could not be found in any version, there may be a typo in the package name.
  Problem 2
    - The requested package jms/serializer-bundle could not be found in any version, there may be a typo in the package name.
  Problem 3
    - Installation request for symfony/framework-standard-edition 2.4.x-dev -> satisfiable by symfony/framework-standard-edition[2.4.x-dev].
    - symfony/framework-standard-edition 2.4.x-dev requires jms/serializer-bundle 0.13.0 -> no matching package found.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

编辑2：我将Symfony降级为〜2.3，并且当我进行更新时，冻结的行已更改
