Php 由于依赖关系，无法安装/路由

我正在尝试将照明/布线添加到Lumen项目中，但每当我尝试通过composer安装它时，都会引发以下错误：

$ 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.

你知道我应该做什么吗？

从

composer.json

中删除：

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

实际上，您不需要它做任何事情，因为您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

，软件包就可以正确安装了。

也遇到了同样的问题。你解决了吗？

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