无法在Laravel 4.1中安装moltin购物车

Question

当我试图安装moltin购物车时，它会显示以下错误

我的作曲家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.*",

    ]
},
"config": {

它显示了以下错误

C:\xampp\htdocs\laravel>composer update

Answer 1

它就在这条错误信息中：

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

你要么更新拉拉，要么找到一个分支的拉拉-车运行4.1。可能是4.2标签
