Docker 撰写：npm ERR！缺少脚本：构建

Question

你好，我不知道我在尝试使用 docker compose 和 postgress 时错在哪里

码头工人撰写 yml：

version: "3.7"
services:
  db:
    image: postgres
    environment:
      POSTGRES_PASSWORD: postgres
      POSTGRES_USER: postgres
      POSTGRES_DB: emasa
    volumes:
      - ./pgdata:/var/lib/postgresql/data
    ports:
      - "5432:5432"
    web:
      image: emasapg
      depends_on:
        - dbs
      ports:
        - "4000:4000"

码头文件

FROM node as builder
WORKDIR usr/app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build


FROM node
WORKDIR usr/app
COPY package*.json ./
RUN npm install --production

COPY --from=builder /usr/app/dist ./dist

COPY ormconfig.docker.json ./ormconfig.json
COPY .env . 

expose 4000
CMD node dist/src/index.js

我的 package.json：

{
  "name": "back-end",
  "version": "0.0.1",
  "description": "Awesome project developed with TypeORM.",
  "devDependencies": {
    "@types/express": "^4.17.3",
    "@types/graphql": "^14.5.0",
    "@types/node": "^13.9.1",
    "ts-node": "8.6.2",
    "typescript": "3.3.3333"
  },
  "dependencies": {
    "apollo-server-express": "^2.11.0",
    "express": "^4.17.1",
    "graphql": "^14.6.0",
    "pg": "^7.3.0",
    "reflect-metadata": "^0.1.13",
    "typeorm": "0.2.24"
  },
  "scripts": {
    "start": "ts-node src/index.ts"
  }
}

错误：

npm 错误！缺少脚本：构建

我的文件结构：

错误从这一行开始：

第 6 行：运行 npm run build

编辑：忘记将 package.json 添加到问题中

它基本上是在抱怨缺少构建脚本，它试图运行它，但它在你的package.json 中丢失了！

我认为您应该尝试更新您的 package.json 文件并添加构建脚本：

{
  "name": "back-end",
  "version": "0.0.1",
  "description": "Awesome project developed with TypeORM.",
  "devDependencies": {
    "@types/express": "^4.17.3",
    "@types/graphql": "^14.5.0",
    "@types/node": "^13.9.1",
    "ts-node": "8.6.2",
    "typescript": "3.3.3333"
  },
  "dependencies": {
    "apollo-server-express": "^2.11.0",
    "express": "^4.17.1",
    "graphql": "^14.6.0",
    "pg": "^7.3.0",
    "reflect-metadata": "^0.1.13",
    "typeorm": "0.2.24"
  },
  "scripts": {
    "start": "ts-node src/index.ts",
    "build": ""  // your build script goes here, "tsc" should be fine
  }
}
