如何在Laravel 5.3中安装Jaxon 2.0

Question

Good day.

I followed the tutorial instruccions to install.

Installation

Add the following lines in the composer.json file, and run the composer update command.

"require": {
    "jaxon-php/jaxon-laravel": "~2.0"
}

But i recieve the following error:

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - The requested package jaxon-php/jaxon-laravel ~2.0 is satisfiable by jaxon-php/jaxon-laravel[v2.0-beta.1, v2.0-beta.2, v2.0-beta.3, v2.0-beta.4, v2.0-beta.5, v2.0-beta.6] but these conflict with your requirements or minimum-stability.

This is my composer.json file:

    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",

    },

    },
    "autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\\": "app/"
        }
    },
    "autoload-dev": {
        "classmap": [
            "tests/TestCase.php"
        ]
    },
    "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"
    }
}

Any ideas? Thank you.

Answer 1

Googling arround i think i found my problem:

Since jaxon is in BETA version and composer default minimun stability requeriments are STABLE, composer failed to install the package.

I added this 2 lines to my composer.json:

"minimum-stability": "beta",
"prefer-stable": true,
