无法在本地运行无服务器的基本示例

Question

我想运行一个基本的无服务器示例& bref示例。

我所做的：

1. npm安装-g无服务器
2. 作曲家要求
3. 供应商/bin/bref init
4. 无服务器调用本地-f hello -docker

我得到了这个错误：

serverless invoke local尝试使用一个名为lambci/lambda:${runtime}的Docker映像，在您的示例中，runtime是phpX.Y。

您在这里看不到这样的图像：

正如评论所述，不要使用--docker。如果需要Docker，可以遵循文献资料并使用以下docker-compose.yml

version: "3.5"

services:
    web:
        image: bref/fpm-dev-gateway
        ports:
            - '8000:80'
        volumes:
            - .:/var/task
        depends_on:
            - php
        environment:
            HANDLER: index.php
    php:
        image: bref/php-74-fpm-dev
        volumes:
            - .:/var/task:ro
