自定义Laravel包rah1595/laravel-drag-menu安装失败求助

我Fork了Laravel拖拽菜单构建包efectn/laravel-menu-builder，为兼容Laravel 10修改了composer.json中的包名为rah1595/laravel-drag-menu，但尝试安装时遇到以下报错：

报错1 #

执行命令 composer require rah1595/laravel-drag-menu 时：

In PackageDiscoveryTrait.php line 368:

  Could not find a matching version of package rah1595/laravel-drag-menu. Check the package spelling, your version co
  nstraint and that the package is available in a stability which matches your minimum-stability (dev).

报错2 #

执行命令 composer require rah1595/laravel-drag-menu:dev-master 时：

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

  Problem 1
    - Root composer.json requires rah1595/laravel-drag-menu, it could not be found in any version, there may be a typo in the package name.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
 - It's a private package and you forgot to add a custom repository to find it

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

我的包的composer.json内容：

    "name": "rah1595/laravel-drag-menu",
    "description": "Wordpress like drag & drop menu builder for Laravel",
    "keywords": ["Laravel", "Menu", "Wordpress", "Builder", "Drag and Drop"],

        }
    ],
    "minimum-stability": "dev",
    "prefer-stable": true
}

我的GitHub仓库地址是rah1595/laravel-drag-menu，希望能像常规Laravel包一样正常安装。

1. 修复包的composer.json问题 #

• 删除无效依赖项：你的包配置里有个不存在的依赖"vendor/package": "1.1.1"，这会导致Composer无法解析依赖，直接删掉这一行。
• 移除仓库配置：不要把自定义仓库写在包自身的composer.json中，仓库配置应该放在要安装该包的Laravel项目的composer.json里。

2. 给仓库打版本标签（推荐） #

如果想让Composer识别稳定版本，给你的GitHub仓库打一个语义化版本标签（比如v1.0.0），这样后续安装可以不用指定dev-master版本。

3. 项目端配置与安装 #

步骤1：修改目标项目的composer.json

在你要安装该包的Laravel项目中，添加自定义仓库和稳定性配置：

"repositories": [
    {
        "type": "vcs",
        "url": "https://github.com/rah1595/laravel-drag-menu"
    }
],
"minimum-stability": "dev",
"prefer-stable": true

步骤2：执行安装命令

• 如果已经打了版本标签，直接执行：

  composer require rah1595/laravel-drag-menu
  

• 如果未打标签，指定开发版本安装：

  composer require rah1595/laravel-drag-menu:dev-master
  

4. 可选：发布到Packagist #

如果希望其他用户无需添加自定义仓库就能安装你的包，可以将GitHub仓库提交到Packagist，这样Composer就能直接从官方源拉取你的包。
