无法在 Laravel 4.1 中安装 moltin 购物车

Question

当我尝试安装 moltin 购物车时，它会显示以下错误

我的 composer json 代码是

{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"require": {
    "laravel/framework": "4.1.*",
    "illuminate/support": "4.1.*",
    "intervention/image": "2.2.*",
    "moltin/laravel-cart": "dev-master"

"autoload": {
    "classmap": [
        "app/commands",
        "app/controllers",
        "app/models",
        "app/database/migrations",
        "app/database/seeds",
        "app/tests/TestCase.php"
    ]
},

        "php artisan optimize"
    ],
    "post-create-project-cmd": [

    ]
},
"config": {
    "preferred-install": "dist"
},

}

显示以下错误

C:\xampp\htdocs\laravel>composer update

Answer 1

就在错误消息中：

moltin/laravel-cart dev-master requires laravel/framework ~5.0

要么更新 laravel，要么找到一个在 4.1 上运行的 laravel-cart 分支。可能是4.2 tag
