Question

我遇到了一个似乎非常受Node / NPM欢迎的问题

我的搜索结果似乎都没有完全解决我的问题......

我使用Restify＆amp; NodeJs ...但是一个简单的npm run start会产生以下错误......

import logger   from 'src/modules/amLogger.js';
^^^^^^

SyntaxError: Unexpected token import

  },
  "description": "example",
  "main": "am.js"
}

这是我的am.js文件

'use strict';

require('dotenv').config();
import logger   from 'src/modules/amLogger.js';
import chalk    from 'chalk';
import util     from 'util';

/**
 * Module Dependencies
 */
const restify   = require('restify'),
    winston     = require('winston'),
    errs        = require('restify-errors'),
    art         = require('ascii-art'),
    compression = require('compression');

// create the Restify Server
const server = restify.createServer({
    name: 'example',
    version: 'v0.0.1',
...

错误发生在import logger from 'src/modules/amLogger.js';但是如果我注释掉这一行错误只会移到下一个导入语句 - 我也尝试在没有'use strict';

我错过了什么？

Node不支持es6导入，你有一篇解释它的文章 https://medium.com/the-node-js-collection/an-update-on-es6-modules-in-node-js-42c958b890c
