【问题描述】：
我遇到了一个似乎在 Node / NPM 中非常流行的问题
我的搜索结果似乎都没有完全解决我的问题...
我正在使用 Restify 和 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';
^^^^^^

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，错误只会移动到下一个导入语句——我也尝试在没有'use strict'; 的情况下运行它
我错过了什么？
