無法安裝，因爲依賴

Question

我想照亮/路由添加到我的流明項目，但每當我試圖通過作曲家安裝它，下面的錯誤被拋出照亮/路由：

$ 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. 

所以我一直在試圖要求合同，雖然幾乎相同的錯誤被拋出告訴我一個更新版本的照明/支持是必需的

反正我真的不知道該怎麼做了，我不能看到我的選擇是什麼。

這裏是我的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 
     } 
} 

你有我應該做的任何想法？從composer.json

Answer 1

降：

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

你其實並不需要任何東西，因爲你不依賴於任何不穩定的包（這就是他們使用什麼）。

當我這樣做，刪除/vendor目錄並運行composer install，包安裝正確。
