Composer - illuminate/redis 安装失败，因为 illuminate/support 的版本不同

Question

我为一个新项目创建了 Lumen 的全新安装，我正在尝试将 Redis 设置为 Cache/Session 驱动程序。通过作曲家，我能够毫无问题地安装 Predis，然后在尝试运行:

composer require illuminate/redis

我收到这个错误，它告诉我 Composer 被混淆了，因为不同的库要求不同版本的 illuminate/support，正如我从 this question:

中了解到的

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Can only install one of: illuminate/support[v5.2.0, v5.1.25].
    - Can only install one of: illuminate/support[v5.2.0, v5.1.25].
    - Can only install one of: illuminate/support[v5.2.0, v5.1.25].
    - illuminate/redis v5.2.0 requires illuminate/support 5.2.* -> satisfiable by illuminate/support[v5.2.0].
    - Installation request for illuminate/redis ^5.2 -> satisfiable by illuminate/redis[v5.2.0].
    - Installation request for illuminate/support == 5.1.25.0 -> satisfiable by illuminate/support[v5.1.25].


Installation failed, reverting ./composer.json to its original content.

下面是我的 composer.json，非常基础：

{
    "name": "laravel/lumen",
    "description": "The Laravel Lumen Framework.",
    "keywords": ["framework", "laravel", "lumen"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=5.5.9",
        "laravel/lumen-framework": "5.1.*",
        "vlucas/phpdotenv": "~1.0",
        "predis/predis": "^1.0"
    },
    "require-dev": {
        "phpunit/phpunit": "~4.0",
        "fzaninotto/faker": "~1.0"
    },
    "autoload": {
        "psr-4": {
            "App\": "app/"
        },
        "classmap": [
            "database/"
        ]
    },
    "autoload-dev": {
        "classmap": [
            "tests/"
        ]
    },
    "config": {
        "preferred-install": "dist"
    }
}

我的问题是，我做错了什么？，上面链接的问题建议手动更改以解决此问题。但我相信设置是如此基本，我应该在这里做错了。

Answer 1

我不得不用 illuminate/redis 的所需版本编辑 composer.json 文件；强制使用相同的版本，如下：

{
    "name": "laravel/lumen",
    "description": "The Laravel Lumen Framework.",
    "keywords": ["framework", "laravel", "lumen"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=5.5.9",
        "laravel/lumen-framework": "5.1.*",
        "vlucas/phpdotenv": "~1.0",
        "predis/predis": "^1.0",
        "illuminate/redis" : "5.1.*"
    },
    "require-dev": {
        "phpunit/phpunit": "~4.0",
        "fzaninotto/faker": "~1.0"
    },
    "autoload": {
        "psr-4": {
            "App\": "app/"
        },
        "classmap": [
            "database/"
        ]
    },
    "autoload-dev": {
        "classmap": [
            "tests/"
        ]
    },
    "config": {
        "preferred-install": "dist"
    }
}
