Question

我正在尝试使用以下命令安装我的作曲家包：

composer install --no-dev --no-scripts

composer.json文件看起来像这样（它与标准的Laravel编写器文件非常相似）：

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=5.5.9",
        "laravel/framework": "5.2.*",
        "doctrine/dbal": "^2.5",
    },
    "require-dev": {
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~4.0",
        "symfony/css-selector": "2.8.*|3.0.*",
        "symfony/dom-crawler": "2.8.*|3.0.*",
        "laravel/homestead": "^5.2",
        "barryvdh/laravel-ide-helper": "^2.3"
    },
    "autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\\": "app/"
        }
    },
    "autoload-dev": {
        "classmap": [
            "tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-root-package-install": [
            "php -r \"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"
    }
}

但是当我尝试在我的生产机器上安装它时（在版本v5.5.9上运行PHP）我收到以下错误：

您的要求无法解析为可安装的软件包。

  Problem 1
    - laravel/homestead v5.4.0 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
    - laravel/homestead v5.3.2 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
    - laravel/homestead v5.3.1 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
    - laravel/homestead v5.3.0 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
    - laravel/homestead v5.2.4 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
    - laravel/homestead v5.2.1 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
    - laravel/homestead v5.2.0 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
    - laravel/homestead 5.2.3 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
    - laravel/homestead 5.2.2 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
    - Installation request for laravel/homestead ^5.2 -> satisfiable by laravel/homestead[5.2.2, 5.2.3, v5.2.0, v5.2.1, v5.2.4, v5.3.0, v5.3.1, v5.3.2, v5.4.0].

所以我的问题如下：

当我说--no-dev并且宅基地是开发包时，为什么宅基地甚至被安装？
如果我确实想在我的生产机器上安装Homestead，我该如何解决上述问题？

Answer 1

--no-dev不应安装dev依赖项。检查生产构建脚本（或者您在生产时运行此脚本时使用的任何脚本），确实添加了--no-dev。

对于问题的第二部分，您可以通过将laravel/homestead包版本更改为~4.0或4.0.5来更准确地使其与您的php版本兼容，从而避免错误。

使用Homestead安装Composer会出现错误“您的要求无法解析为可安装的软件包”
