尝试加载ZendFramework 2骨架应用程序时出现Composer错误

Question

我最近开始学习ZendFramework2，并且我需要运行php composer.phar install来初始化骨架应用程序。我已经成功执行了以下指令：

git clone git://github.com/zendframework/ZendSkeletonApplication.git

我知道我有良好的出站连接。当我到达需要安装作曲家的部分时，我的问题就出现了。我得到以下输出：

rt_zapzap@zingzing1:/var/www/ZendApp$ composer install
Loading composer repositories with package information
Installing dependencies
- Installing zendframework/zendframework (2.2.0rc3)
Downloading: connection...
[Composer\Downloader\TransportException]
The "https://api.github.com/repos/zendframework/zf2/zipball/release-2.2.0rc3" file could not be downloaded (HTTP/1.0 400 Bad Request)



install [--prefer-source] [--prefer-dist] [--dry-run] [--dev] [--no-dev] [--no-custom-    installers] [--no-scripts] [--no-progress] [-v|vv|vvv|--verbose] [-o|--optimize-autoloader]

作为参考，composer.json看起来像

{
    "name": "zendframework/skeleton-application",
    "description": "Skeleton Application for ZF2",
    "license": "BSD-3-Clause",
    "keywords": [
        "framework",
        "zf2"
    ],
    "homepage": "http://framework.zend.com/",
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": ">2.2.0rc1"
    }
}

我想知道在哪里纠正这个问题？
