Zend - 未定义 class TableGateway

Question

当我从文档中复制时：

use Zend\Db\TableGateway\TableGateway;

php暴风雨表演

未定义class TableGateway。

有什么问题吗？

我试图在整个项目中搜索 "TableGateway" 但我没有找到 classname.

我再次尝试了运行命令

 composer install

以防出现问题，但它显示一切都已安装。 composer.json 看起来像这样：

{
    "name": "zendframework/skeleton-application",
    "description": "Skeleton Application for Zend Framework zend-mvc applications",
    "type": "project",
    "license": "BSD-3-Clause",
    "keywords": [
        "framework",
        "mvc",
        "zf"
    ],
    "homepage": "http://framework.zend.com/",
    "minimum-stability": "dev",
    "prefer-stable": true,
    "require": {
        "php": "^5.6 || ^7.0",
        "zendframework/zend-component-installer": "^1.0 || ^0.3 || ^1.0.0-dev@dev",
        "zendframework/zend-mvc": "^3.0.1",
        "zfcampus/zf-development-mode": "^3.0",
        "webonyx/graphql-php": "^0.8"
    },
    "autoload": {
        "psr-4": {
            "Application\": "module/Application/src/"
        }
    },
    "autoload-dev": {
        "psr-4": {
            "ApplicationTest\": "module/Application/test/"
        }
    },
    "extra": [],
    "scripts": {
        "cs-check": "phpcs",
        "cs-fix": "phpcbf",
        "development-disable": "zf-development-mode disable",
        "development-enable": "zf-development-mode enable",
        "development-status": "zf-development-mode status",
        "post-create-project-cmd": [
            "@development-enable"
        ],
        "serve": "php -S 0.0.0.0:8080 -t public/ public/index.php",
        "test": "phpunit"
    }
}

怎么了？

如果要从中使用类，则需要安装数据库组件：

composer require zendframework/zend-db
