IBM bluemix 上的 ES6 模块语法支持
ES6 modules syntax support on IBM bluemix
我有一个使用 ES6 导入语句的应用程序。我尝试将它部署在 ibm cloudfoundry 上。日志显示它从节点 6.8.0 开始。该应用程序抱怨:
Unexpected token import
我在我的 windows 10 桌面上启动了应用程序,节点为 6.8.0,它运行完美。我 运行 :
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' }
输出在我的机器上是相同的,在我的机器上应用程序工作,而在 bluemix 服务器上它不工作。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
}
server/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';

尽管 es6 标准定义了 import 语句,但节点本身不支持它(目前)。
