如何解决作曲家需求冲突？

Question

我正在测试 Laravel Framework 新的 5.1 版本。

我想安装著名的 barryvdh/laravel-ide-helper 包。

A知道问题是：barryvdh/laravel-ide-helper require illuminate/filesystem: 5.0.x and laravel/framework require illuminate/filesystem: 5.1.x.

如何配置我的 composer.json 文件？

注意：我的 composer.json 文件中有 "minimum-stability": "dev" 和 "prefer-stable": true。

安装时，出现此错误：

Problem 1
    - Conclusion: remove laravel/framework 5.1.x-dev
    - barryvdh/laravel-ide-helper 2.0.x-dev requires illuminate/filesystem 5.0.x -> satisfiable by illuminate/filesystem[5.0.x-dev, v5.0.0, v5.0.22, v5.0.25, v5.0.26, v5.0.28, v5.0.4].

    - don't install illuminate/filesystem v5.0.0|don't install laravel/framework 5.1.x-dev
    - don't install illuminate/filesystem v5.0.22|don't install laravel/framework 5.1.x-dev
    - don't install illuminate/filesystem v5.0.25|don't install laravel/framework 5.1.x-dev
    - don't install illuminate/filesystem v5.0.26|don't install laravel/framework 5.1.x-dev
    - don't install illuminate/filesystem v5.0.28|don't install laravel/framework 5.1.x-dev
    - don't install illuminate/filesystem v5.0.4|don't install laravel/framework 5.1.x-dev
    - Installation request for laravel/framework 5.1.* -> satisfiable by laravel/framework[5.1.x-dev].
    - Installation request for barryvdh/laravel-ide-helper ^2.0@dev -> satisfiable by barryvdh/laravel-ide-helper[2.0.x-dev, v2.0.0, v2.0.1, v2.0.2, v2.0.3].

我已经尝试了以下所有命令，结果相同...

$ composer require barryvdh/laravel-ide-helper,
$ composer require barryvdh/laravel-ide-helper:@dev --dev
$ composer require barryvdh/laravel-ide-helper --dev --update-with-dependencies

我也尝试在 composer.json 文件上创建一个别名：

"require": {
    "laravel/framework": "5.1.*",
    "illuminate/filesystem": "5.1.x-dev as 5.0.28"
},

然后出现这个错误：

  Problem 1
    - Installation request for barryvdh/laravel-ide-helper dev-master -> satisfiable by barryvdh/laravel-ide-helper[dev-master].
    - Conclusion: remove laravel/framework 5.1.x-dev
    - Conclusion: don't install laravel/framework 5.1.x-dev
    - barryvdh/laravel-ide-helper dev-master requires illuminate/filesystem 5.0.x -> satisfiable by illuminate/filesystem[5.0.x-dev, 5.0.28].
    - don't install illuminate/filesystem 5.0.x-dev|don't install laravel/framework 5.1.x-dev
    - don't install illuminate/filesystem 5.0.28|don't install laravel/framework 5.1.x-dev
    - Installation request for laravel/framework 5.1.* -> satisfiable by laravel/framework[5.1.x-dev].

这是我的 composer.json 文件：

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "laravel/framework": "5.1.*",
        "illuminate/filesystem": "5.1.x-dev as 5.0.28"
    },
    "require-dev": {
        "phpunit/phpunit": "~4.0",
        "phpspec/phpspec": "~2.1"
    },
    "autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "Portal\": "app/"
        }
    },
    "autoload-dev": {
        "classmap": [
            "tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-install-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-create-project-cmd": [
            "php -r \"copy('.env.example', '.env');\"",
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist"
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

Answer 1

核心问题源于对 5.0.x 的过度限制版本约束。我不知道这是否有充分的理由。

一个选择是将 laravel-ide-helper 分叉到您自己的仓库中，将版本限制更改为 ^5.0 之类的内容（也许还有包名称），然后将您的分叉仓库添加为 git 存储库在您的 composer.json 文件中。这至少可以让您看到它是否按预期工作。

Answer 2

正如您所指出的，问题是您安装了 Laravel 5.1（顺便说一句，它仍然不稳定，我不建议使用它 atm）并且该软件包需要 5.0.*.

有几种解决方案：

在 laravel ide 帮助库中创建一个问题，要求作者放宽版本限制。请注意，此库与版本密切相关，这可能是版本限制如此严格的原因。
不要安装不稳定的5.1版本，而是坚持使用5.0，等5.1发布和更新包时使用。

Answer 3

我已经用 composer.json 文件中的一个别名解决了问题：

"require": {
    "laravel/framework": "5.1.x-dev as 5.0.28"
},

所以，laravel/framework 有 "illuminate/filesystem": "5.1.x-dev" 而 barryvdh/laravel-ide-helper 认为有 "illuminate/filesystem": "5.0.28"

我的第一个方法：

"require": {
    "laravel/framework": "5.1.*",
    "illuminate/filesystem": "5.1.x-dev as 5.0.28"
},

它不起作用，因为 illuminate/filesystem 它被 laravel/framework 用作子树，然后我必须为 laravel/framework 设置别名而不是 illuminate/filesystem。
