Laravel Composer 包无法安装

Question

我正在尝试在 Laravel 中安装 Zizaco。 (https://github.com/Zizaco/entrust) 当我将 "zizaco/entrust": "dev-laravel-5" 添加到 require 然后在 cmd 中执行 composer update 时，它​​没有说明要安装或更新。

这是我的整个 composer.json 文件：

{
    "name": "classpreloader/classpreloader",
    "description": "Helps class loading performance by generating a single PHP file containing all of the autoloaded files for a specific use case",
    "keywords": ["autoload", "class", "preload"],
    "license": "MIT",
    "authors": [
        {
            "name": "Michael Dowling",
            "email": "mtdowling@gmail.com"
        },
        {
            "name": "Graham Campbell",
            "email": "graham@alt-three.com"
        }
    ],
    "require":{
        "php": ">=5.5.9",
        "nikic/php-parser": "~1.3",
        "zizaco/entrust": "dev-laravel-5"
    },

    "require-dev":{
        "phpunit/phpunit": "~4.0"
    },
    "autoload": {
        "psr-4": {
            "ClassPreloader\\": "src/"
        }
    },
    "autoload-dev": {
        "classmap": ["tests/stubs/"]
    },
    "config": {
        "preferred-install": "dist"
    },
    "extra": {
        "branch-alias": {
            "dev-master": "2.0-dev"
        }
    }
}

我在这里做错了什么>>？

谢谢

De 文档告诉我：

为了安装 Entrust，我们只需要将这一行添加到 composer.json 文件中：

"zizaco/entrust": "dev-laravel-5"

You should have something like this:

"require": {
    "php": ">=5.5.9",
    "laravel/framework": "5.1.*",
    "laravelcollective/html": "5.1.*",
   "zizaco/entrust": "dev-laravel-5"
},

Next, run composer update to install Entrust.

Answer 1

缺少一个逗号 (,)。

纠正它：

"require":{
    "laravel/framework": "5.1.*",
    "nikic/php-parser": "~1.3", 
    "zizaco/entrust": "dev-laravel-5"
},

Answer 2

"nikic/php-parser": "~1.3"

后面缺少逗号

您的 composer.json 应该包含：

"require":{
    "php": ">=5.5.9",
    "nikic/php-parser": "~1.3",
    "zizaco/entrust": "dev-laravel-5"
},
