Composer - vcs 上请求的包问题

我分叉了https://github.com/calebporzio/onboard https://github.com/calebporzio/onboard to https://github.com/mpjraaij/onboard/tree/dev-bugfix https://github.com/mpjraaij/onboard/tree/dev-bugfix

我的作曲家文件已更新为

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "repositories": [
        {
            ...
        },
        {
            "type": "vcs",
            "url": "https://github.com/mpjraaij/onboard"
        }
    ],
    "require": {
        ...
        "calebporzio/onboard": "dev-bugfix",
        ...
    },

        ],
        "psr-4": {
            "App\\": "app/"
        }
    },

            ]
        }
    },
    "scripts": {
        "post-root-package-install": [
            "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ],

    "config": {
        "preferred-install": "dist",
        "sort-packages": true,
        "optimize-autoloader": true
    }
}

但是当我运行时出现以下错误composer update

您的要求无法解析为一组可安装的软件包。

问题1 - 请求的包 calebporzio/onboard dev-bugfix 作为 calebporzio/onboard[dev-master, v1.0, v1.1, dev-dev-bugfix] 存在，但这些被您的约束拒绝。

我该如何解决这个问题？

解决方案其实就在错误信息中：The requested package ... exists as calebporzio/onboard[dev-master, v1.0, v1.1, dev-dev-bugfix].

在 Composer 中，要引用任何看起来不像版本的分支，您需要添加dev-在它的前面。要参考master分支，你会使用dev-master。同样的事情也适用于此。

因此要引用一个名为dev-bugfix，你需要使用dev-dev-bugfix在你的composer.json文件，正如错误消息所建议的那样。
