由于依赖关系，无法安装Illuminate/routing

Question

我正试图将照明/路由添加到我的Lumen项目中，但每当我试图通过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签订合同，尽管同样的错误告诉我需要更新版本的照明/支持

无论如何，我真的不知道该怎么办了，我看不出我有什么选择。

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
        }
}

你知道我该怎么做吗？

Answer 1

从composer.json:中删除

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

实际上，你不需要它，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目录并运行composer install，软件包就会正确安装。
