php - 无法将要求解析为一组可安装的软件包

Question

我试图在 laravel-starter-kit 中安装 jasonlewis/enhanced-router 包，但当我运行 composer update 时它没有安装并出现一些错误。最初我认为问题出在 jasonlewis/enhanced-router ("jasonlewis/enhanced-router": "dev-master") 的 composer 行，但我删除了它并遇到了同样的错误。

我试图搜索一些类似的问题，但无法弄清楚我遇到的依赖问题是什么。

下面是我运行composer update后得到的结果:

Answer 1

欢迎使用 Composer 最糟糕的功能!

所以问题是您的依赖项中存在难以发现的冲突。

您的 composer.json 中有 "laravel/framework": "4.0.*", 的要求。您还需要 "zizaco/confide": "dev-master"

在 github 中的 composer.json 中查找“zizaco/confide”，我们看到:

"illuminate/support": "4.1.x",

导致您出现问题的 Composer 功能是 replace 关键字在整个 PACKAGIST 中全局操作。

所以因为 'illuminate/support' package is replace'd by Laravel itself当 Composer 尝试满足 "illuminate/support": "4.1.x"的要求时，它实际上会尝试下载 laravel 4.1.x 版本。

这与您对 laravel 版本 4.0.* 的要求相冲突，因此无法解析依赖项集。

我认为您的问题可能没有简单的解决方案。

我将建议指定一个较早版本的 zizaco/confide 而不是 dev-master，它依赖于 4.0.x 而不是 4.1.x 的Illumination/support 版本——但这意味着从 zizaco/confide 3 切换。 x 到 2.x，这可能是 Not Acceptable 。

唯一的其他选择是将您的要求从 laravel 4.0.x 更改为 4.1.* - 这可能会或可能不会接受，具体取决于您的工作量。
