Composer + Rocketeer + ZF2- 由于需求冲突无法安装 Rocketeer

Question

有人可以告诉我如何解决这个问题吗？

Rocketeer 在空目录中安装得很好，但不能与我现有的项目一起安装，不知道为什么。

需要安装什么？

 - Installation request for symfony/console == 2.6.6.0 -> satisfiable by symfony/console[v2.6.6].

composer.json

{
    "name": "zendframework/skeleton-application",
    "description": "Skeleton Application for ZF2",
    "license": "BSD-3-Clause",
    "keywords": [
        "framework",
        "zf2"
    ],
    "homepage": "http://framework.zend.com/",
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": "~2.3",
        "doctrine/doctrine-module": "dev-master",
        "doctrine/doctrine-orm-module": "dev-master",
        "zendframework/zend-developer-tools": "dev-master",
        "mandrill/mandrill": "1.0.*"
    }
}

命令

composer require anahkiasen/rocketeer

Answer 1

为什么没有安装？

Zend Skeleton 安装的依赖项在 2.6.6 版本中使用 symfony/console。

"anahkiasen/rocketeer" 在 ~4.2 版本中需要 "illuminate/console"，它本身在 2.5.* 版本中需要 "symfony/console"。

Composer 无法安装新包，因为 symfony/console 已安装的 2.6.6 版本将被保留，但与新包依赖项的要求不兼容（2.5.* 不允许使用 2.6 版本.6).

您可以尝试手动添加您的新包，然后运行 composer update。如果 2.5 版骨架包也允许 symfony/console，这将解析为一组可安装的包。
