node.js - 运行连接到 MongoDB 云集群的 nodejs 应用程序时，Docker-compose 给出：“node|SyntaxError: Unexpected token import”错误

问题描述

我有一个在云上使用 MongoDb 集群的工作 nodejs 应用程序。我正在尝试使用 docker-compose up 对其进行 dockerize，但我不断收到此错误：

nodejs |从 'mongodb' 导入 Mongodb; 节点 | ^^^^^^ nodejs | SyntaxError：意外的令牌导入

这是我的 dockerFile：

FROM node:12.16.1 as build
WORKDIR /app
COPY . /app
RUN npm install
RUN npm run build
COPY . .
EXPOSE 80
CMD ["node", "app.js", "daemon off;"]

这是我的 docker-compose.yml：

version: '3'

services:
  nodejs:
    build:
      context: .
      dockerfile: Dockerfile
    image: nodejs
    container_name: nodejs
    restart: unless-stopped
    env_file: .env
    volumes:
      - node_modules:/node_modules
    command: node app.js 

  
volumes:
    node_modules:

这是我的 package.JSON 文件：

解决方案

从版本13.2.0 开始支持该import语句浏览器兼容性表

或者从版本 12.0.0 开始，用户必须使用--experimental-modules运行时标志显式启用此功能。

确保重建您的图像。docker-compose up --build将在启动容器之前构建您的图像。
