Question

我有一个使用ES6导入语句的应用。我尝试在ibm cloudfoundry上部署它。日志显示它从节点6.8.0开始。该应用程序抱怨：

 Unexpected token import

我在Windows 10桌面上启动了应用程序，节点为6.8.0，运行完美无缺。我跑了：

console.log(process.versions);

这是输出：

{ http_parser: '2.7.0',
  node: '6.8.0',
  v8: '5.1.281.84',
  uv: '1.9.1',
  zlib: '1.2.8',
  ares: '1.10.1-DEV',
  icu: '57.1',
  modules: '48',
  openssl: '1.0.2j' }

在我的应用程序运行的机器上以及在它没有的bluemix服务器上输出相同。这是我的Package.json：

    {
  "name": "bluemixtest",
  "version": "0.0.0",
  "main": "server/app.js",
  "dependencies": {
  },
  "devDependencies": {
  },
  "engines": {
    "node": "6.8.0"
  },
  "scripts": {
    "start": "node --harmony_modules server/app.js"
  },
  "private": true
}

服务器/ app.js：

'use strict';
import express from 'express';
import mongoose from 'mongoose';

日志中的启动错误：

/home/vcap/app/server/app.js:7
import express from 'express';

虽然es6标准定义了import语句，但本地（尚未）节点不支持它。 "Import" ES6 for Node

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import

IBM bluemix上的ES6模块语法支持
