如何使用 babel 将我的 nodejs 代码投入生产？

Question

我配置了我的 babel 环境但是遇到了一些问题

我的错误：

(function (exports, require, module, __filename, __dirname) { import mongoose from 'mongoose' ^^^^^^^^

语法错误：意外的标识符

我的 package.json ：

    "babel-preset-es2015": "^6.24.1",
    "body-parser": "^1.19.0",

    "mongoose": "^5.6.8",
    "nodemailer": "^6.3.0",
    "nodemon": "^1.19.1"
  },
  "scripts": {
    "clean": "rm -rf build && mkdir build",
    "build": "yarn clean && yarn build-babel",
    "build-babel": "babel -d ./build ./src -s",
    "db": "mongod --dbpath ~/data/db",
    "deploy": "yarn build && yarn start",
    "srv:dev": "DEBUG=server:* node_modules/.bin/nodemon src/server.js --exec babel-node --",
    "start": "node ./build/server.js",
    "stop": "pm2 stop ./build/server.js",
    "test": "nodemon --exec babel-node src/server.js"
  },

似乎与这个问题有关：https://github.com/builderbook/builderbook/issues/97

他们的解决方法是在--exec babel-node 之后添加--presets=@babel/preset-env。
