composer 从两个 composer.json 文件安装

Question

我有多个 composer.json 具有多个单独的依赖项，我想使用单个 composer install 命令在两个 composer.json 中安装所有依赖项。

位置是这样的：

| - composer.json
| - Custom
    | - Package1
        | - composer.json

第一个composer.json

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=5.6.4",
        "barryvdh/laravel-debugbar": "^2.3",
        "laravel/framework": "5.4.*",
        "laravel/tinker": "~1.0",
        "laravelcollective/html": "^5.4.0"
    },
    "require-dev": {
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~5.7",
        "symfony/css-selector": "3.1.*",
        "symfony/dom-crawler": "3.1.*"
    },
    "autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\": "app/",
        }
    },
    "autoload-dev": {
        "psr-4": {
          "Tests\": "tests/"
        }
    },
    "scripts": {
        "post-root-package-install": [
            "php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ],
        "post-install-cmd": [
            "Illuminate\Foundation\ComposerScripts::postInstall",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "Illuminate\Foundation\ComposerScripts::postUpdate",
            "php artisan optimize"
        ]
    },
    "config": {
        "preferred-install": "dist",
        "sort-packages": true,
        "optimize-autoloader": true
    }
}

Package1 目录中的第二个 composer.json

{
    "name": "custom/package1",
    "description": "",
    "require": {
        "php": ">=5.6",
        "composer/installers": "~1.0",
        "lavary/laravel-menu": "1.7.1"
    },
    "autoload": {
        "psr-4": {
            "Custom\Package1\": ""
        }
    }
}

我想将 Package1 内的 lavary/laravel-menu 安装到安装了所有默认包的主要供应商目录。

|- vendor  //<==want here
| - composer.json
    | - Custom
        | - Package1
            | - vendor  //<== not here
            | - composer.json

我测试过这个解决方案：

像这样：

{
    "config": {
        "vendor-dir": "../../vendor/"
    }
}

这会安装软件包，但我们需要进入第二个 composer.json 而不是主 composer.json 并从第一个 composer.json.

中删除已安装的软件包

如何在不进入单个供应商目录中的第二个或多个 composer.json 的情况下从主 composer.json 安装所有依赖项？

Answer 1

经过一些研究和建议后，我发现有多种方法可以实现此解决方案。

使用外部包维护依赖。

感谢 rickdenhaan 让我知道

Composer 合并插件

https://github.com/wikimedia/composer-merge-plugin

首先我们需要这个包：

composer require wikimedia/composer-merge-plugin

那么我的composer.json就变成了这样：

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=5.6.4",
        "barryvdh/laravel-debugbar": "^2.3",
        "laravel/framework": "5.4.*",
        "laravel/tinker": "~1.0",
        "wikimedia/composer-merge-plugin": "^1.4"
    },
    "require-dev": {
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~5.7",
        "symfony/css-selector": "3.1.*",
        "symfony/dom-crawler": "3.1.*"
    },
    "autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\": "app/"
        }
    },
    "autoload-dev": {
        "psr-4": {
          "Tests\": "tests/"
        }
    },
    "scripts": {
        "post-root-package-install": [
            "php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ],
        "post-install-cmd": [
            "Illuminate\Foundation\ComposerScripts::postInstall",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "Illuminate\Foundation\ComposerScripts::postUpdate",
            "php artisan optimize"
        ]
    },
    "config": {
        "preferred-install": "dist",
        "sort-packages": true,
        "optimize-autoloader": true
    },
    "extra": {
        "merge-plugin": {
            "include": [
                "Custom/*/composer.json"
            ],
            "recurse": true,
            "replace": false,
            "ignore-duplicates": true,
            "merge-dev": true,
            "merge-extra": false,
            "merge-extra-deep": false,
            "merge-scripts": true
        }
    }
}

现在，运行

composer install

或

 composer update

然后你在每个目录中的composer.json将被合并到默认的vendor目录中。

下一个解决方案可能是将包发布到 packagist 并在 composer.json 中要求并且在 composer install 期间将安装所有依赖项。

就像 Asgardcms 所做的那样。
正在将私有存储库添加到 composer.json。

Configuring composer.json with private bitbucket mercurial repository
此选项需要将元包的composer.json添加到主composer.json文件中。

（我不确定这个选项，但感谢 JParkinson1991 知道这个解决方案的人可以添加这个选项的解释。添加只是为了让别人知道这个解决方案存在。）

第一个解决方案适合我的情况。希望这对花费大量时间搜索的人有所帮助。
