由于依赖关系无法安装 Illuminate/routing

Question

我正在尝试将 illuminate/routing 添加到我的 Lumen 项目，但每当我尝试通过 Composer 安装它时，都会抛出以下错误：

$ composer require illuminate/routing Using version ^5.1 for illuminate/routing ./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - The requested package laravel/lumen-framework == 5.0.10.0 could not be found.   Problem 2
    - Installation request for illuminate/contracts == 5.0.33.0 -> satisfiable by illuminate/contracts[v5.0.33].
    - illuminate/routing v5.1.1 requires illuminate/contracts 5.1.* -> satisfiable by illuminate/contracts[v5.1.1].
    - illuminate/routing v5.1.2 requires illuminate/contracts 5.1.* -> satisfiable by illuminate/contracts[v5.1.1].
    - Conclusion: don't install illuminate/contracts v5.1.1
    - Installation request for illuminate/routing ^5.1 -> satisfiable by illuminate/routing[v5.1.1, v5.1.2].

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting    see <https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion> for more details.

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

Installation failed, reverting ./composer.json to its original content.

所以我一直在尝试要求合同，尽管抛出了几乎相同的错误告诉我需要更新版本的 illuminate/support

反正我真的不知道该怎么办了，我看不到我有什么选择。

这是我的composer.json：

{
    "name": "laravel/lumen",
        "description": "The Laravel Lumen Framework.",
        "keywords": ["framework", "laravel", "lumen"],
        "license": "MIT",
        "type": "project",
        "require": {

            "laravel/lumen-framework": "5.1.*",
            "vlucas/phpdotenv": "~1.0",
            "tymon/jwt-auth": "^0.5.4",
        "basicit/lumen-vendor-publish": "^1.0",
        "illuminate/routing": "4"
        },
        "require-dev": {
            "phpunit/phpunit": "~4.0"
        },
        "autoload": {
            "psr-4": {
                "App\": "app/"
            },
            "classmap": [
                "database/"
                ],
            "files": [
                "app/helpers.php"
                ]
        },
        "autoload-dev": {
            "classmap": [
                "tests/"
                ]
        },
        "config": {
            "minimum-stability": "dev",
            "prefer-stable": true
        }
}

你知道我应该做什么吗？

Answer 1

从composer.json掉落：

"config": {
    "minimum-stability": "dev",
    "prefer-stable": true
}

你实际上什么都不需要它，因为你不依赖任何不稳定的包（这就是它们的用途）。

当我这样做时，删除 /vendor 目录和运行 composer install，软件包安装正确。
