我有一个SilverStripe站点，其中包含以下编写器。json文件：

{
    "name": "silverstripe/installer",
    "description": "The SilverStripe Framework Installer",
    "require": {
        "php": ">=5.3.2",
        "silverstripe/cms": "3.2.1",
        "silverstripe/framework": "3.2.1",
        "silverstripe-themes/simple": "*",
        "silverstripe/userforms": "*",
        "silverstripe/widgets": "*",
        "silverstripe/spamprotection": "*",
        "silverstripe/blog": "dev-master",
        "silverstripe/comments": "dev-master",
        "silverstripe/lumberjack": "~1.1",
        "undefinedoffset/sortablegridfield": "dev-master",
        "axllent/silverstripe-version-truncator": "dev-master",
        "unclecheese/betterbuttons": "dev-master",
        "jonom/focuspoint": "dev-master",
        "silverbusters/silverstripe-simplelistfield": "dev-master"
    },
    "config": {
        "process-timeout": 600  
    },
    "minimum-stability": "dev"
}

当我尝试在Apple终端中执行此脚本时，使用phpcomposer.phar安装-dev，我收到以下错误消息：

使用包信息加载composer存储库

安装依赖项（包括require dev）无法将您的需求解析为一组可安装的包。

这在一月初对我来说很有效。我应该如何修改我的JSON文件，使其正常工作？
