未使用自定义 packages.json 找到 Composer 包

Question

我有一个自定义 packages.json 文件，其中包含以下内容：

{
"packages": {
    "dtcmedia/wordpress": {
        "3.9.1": {
            "name": "dtcmedia/wordpress",
            "version": "3.9.1",
            "version_normalized": "3.9.1.0",
            "source": {
                "type": "git",
                "url": "https://github.com/WordPress/WordPress",
                "reference": "3.9.1"
            },
            "dist": {
                "type": "zip",
                "url": "http://wordpress.org/wordpress-3.9.1.zip"
            },
            "require": {
                "johnpbloch/wordpress-core-installer": "~0.1"
            },
            "type": "wordpress-core"
            }
        }
    }
}

此文件可在网络服务器的 webroot 上找到。我项目中的 composer.json 如下所示：

{
"name": "dtcmedia/wp-startup",
"description": "DTC Media WordPress Startup",
"type": "wp-startup",
"authors": [
    {
        "name": "Roy Janssen",
        "homepage": "http://www.dtcmedia.nl",
        "role": "Author"
    }
],
"repositories": [
    {
        "type": "composer",
        "url": "http://dtcmediainternet.nl"
    },
    {
        "type":"composer",
        "url":"http://wpackagist.org"
    }
],
"require": {
    "php": ">=5.3.0",
    "dtcmedia/wordpress": "*",
    "dtcmedia/dtcmedia-occasionmodule-portalkoppeling": "2.0.*"
},
"extra": {
    "installer-name": "wp-startup",
    "installer-paths": {
        "content/plugins/{$name}/": ["type:wordpress-plugin"]
    }
}
}

现在使用命令 $ composer show dtcmedia/wordpress 结果如下： [无效参数异常]
找不到包 dtcmedia/wordpress

详细输出如下所示：

composer show dtcmedia/wordpress -vvv

您的 composer.json 解决了您所拥有的软件包，没有问题：

C:\server\dtcmedia>composer show dtcmedia/wordpress
name     : dtcmedia/wordpress
descrip. :
keywords :
versions : 3.9.1
type     : wordpress-core
license  :
source   : [git] https://github.com/WordPress/WordPress 3.9.1
dist     : [zip] http://wordpress.org/wordpress-3.9.1.zip
names    : dtcmedia/wordpress

requires
johnpbloch/wordpress-core-installer ~0.1

可能是临时问题，例如上传的 packages.json 损坏或其他问题。

我还建议使用johnpbloch/wordpress WordPress 核心包。
