Php 我得到；您的要求无法解析为一组可安装的软件包。”；当我运行composer update时

我用Laravel5.2编写了一个应用程序。此应用程序具有模块/软件包。所有软件包都将位于名为

modules

的文件夹中

我的第一个软件包位于名为

modules/Mikea/Surveys

的文件夹中

Mikea

是供应商的名称，

Surveys

是模块/包的名称。每个包都有自己的

composer.json

文件，允许我使用自己的composer配置配置每个包。（我目前有一个软件包，但以后可以有更多）

在我的主composer.json文件中，我在repositories部分使用type，就像您在下面的composer.json文件中看到的那样

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=5.5.9",
        "laravel/framework": "5.2.*",
        "laravelcollective/html": "5.2.x-dev",
        "mikea/surveys": "*"
    },
    "require-dev": {
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~4.0",
        "phpspec/phpspec": "~2.1",
        "symfony/dom-crawler": "~3.0",
        "symfony/css-selector": " ~3.0"
    },
    "repositories": [
        {
            "type": "path",
            "url": "modules/Mikea/Surveys"
        }
    ],
    "autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\\": "app/",
            "Modules\\": "modules/"
        }
    },
    "autoload-dev": {
        "classmap": [
            "tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-install-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "pre-update-cmd": [
            "php artisan clear-compiled"
        ],
        "post-update-cmd": [
            "php artisan optimize"
        ],
        "post-root-package-install": [
            "php -r \"copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist"
    }
}

在第二个composer.json文件“包文件”中，我有以下内容

{
    "name": "mikea/surveys",
    "type": "library",
    "description": "Survey System",
    "authors": [
        {
            "name": "Mike A",
            "email": "some@email.com"
        }
    ],
    "repositories": [
        {
            "type": "package",
            "package": {
                "name": "mikea/surveys",
                "version": "0.1.0",
                "source": {
                    "type": "path",
                    "url": "modules/Mikea/Surveys"
                }
            }
        }
    ],
    "require": {
        "php": ">=5.4.0"
    },
    "autoload": {
        "classmap": [
            "database/migrations",
            "database/seeds"
        ],
        "psr-4": {
            "mikea\\Surveys\\": "src/"
        }
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

当我运行

composer update

时，我得到以下错误

F:\xampp\htdocs\proj>composer update
> php artisan clear-compiled
Loading composer repositories with package information
Updating dependencies (including require-dev)

我做错了什么？为什么会出现这个错误？

我想我已经解决了

我不得不像这样在第二个

composer.json

文件中添加一个“version”标记。至少添加“版本”可以让我运行命令时不会出错

{
    "name": "mikea/surveys",
    "type": "library",
    "description": "Survey System",
    "version": "0.1.0",
    "authors": [
        {
            "name": "Mike A",
            "email": "some@email.com"
        }
    ],
    "require": {
        "php": ">=5.4.0"
    },
    "autoload": {
        "classmap": [
            "database/migrations",
            "database/seeds"
        ],
        "psr-4": {
            "mikea\\Surveys\\": "src/"
        }
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

文件系统中是否存在

modules/Mikea/Surveys

@ceejayoz是的。它位于

应用程序

，

数据库

。。。。foldersTry

/modules/Mikea/Surveys

，并确保

modules/Mikea/Surveys/composer.json

是有效的json。@ceejayoz我在哪里使用

/modules/Mikea/Surveys

我试图在存储库url中使用它，但仍然出现相同的错误？
