Node.js Docker撰写：npm错误！缺少脚本：构建

你好，我不知道我在尝试使用docker compose with postgress时哪里错了

docker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"

dockerfile

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

my 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：

错误从此行开始：

第6行：运行npm运行构建

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，它尝试运行它，但在您的

包中缺少它。json

我认为您应该尝试更新

package.json

文件并添加一个构建脚本：

{
  "name": "back-end",
  "version": "0.0.1",
  "description": "Awesome project developed with TypeORM.",
  "devDependencies": {
    "@types/express": "^4.17.3",

  },
  "dependencies": {

  "scripts": {

    "build": ""  // your build script goes here, "tsc" should be fine

文件吗？@WaLid LamRaoui done broit基本上是在抱怨缺少构建脚本，它试图运行构建脚本，但它丢失了，请更新问题并发布您的

文件好吗？@WaLid LamRaoui done brohi brohi brother谢谢您的帮助可以帮助我：步骤13/15:COPY.env。复制失败：stat/var/lib/docker/tmp/docker-builder209795817/.env:没有这样的文件或目录我复制这个时遇到了问题：COPY--from=builder/usr/app/dist./dist你让我对第二条评论感到困惑，失败的步骤是什么？步骤13/15的意思是：
COPY.env.
我认为它应该失败，在这种情况下，我认为您只需要在项目的根目录中创建一个
.env
文件，因为它不存在。这有帮助吗？嗨，兄弟，您能帮我解决这个问题吗？嗨，兄弟，谢谢你的帮助。你可以帮我做这个：步骤13/15:COPY.env。复制失败：stat/var/lib/docker/tmp/docker-builder209795817/.env:没有这样的文件或目录我复制这个时遇到了问题：COPY--from=builder/usr/app/dist./dist你让我对第二条评论感到困惑，失败的步骤是什么？步骤13/15的意思是：
