使用 --experimental-modules 在 Node 中导入 ES6 [英] ES6 imports in Node with --experimental-modules

问题描述

尝试在带有 -experimental-modules 标志的节点中使用 ES6 导入.具体:

Trying to use ES6 imports in node with the -experimental-modules flag. Specifically:

mkdir ma
cd ma
npm init
npm i --save moving-averages
touch index.mjs

现在将以下代码放入 index.mjs:

Now place the following code in index.mjs:

import {
ma, dma, ema, sma, wma
} from 'moving-averages'

ma([1, 2, 3, 4, 5], 2) 

结果是:

file:///home/ole/ma/index.mjs:2
  ma, dma, ema, sma, wma
  ^^
SyntaxError: The requested module does not provide an export named 'ma'
    at ModuleJob._instantiate (internal/loader/ModuleJob.js:86:19)
    at <anonymous>

想法?

推荐答案

移动平均线目前只有一个默认导出.您将需要导入整个模块，然后您可以选择解构参数.

Moving averages currently only has a single default export. You will need to import the whole module and then you have the option to de-structure the arguments.

import movingAverages from 'moving-averages'

const {ma, dma, ema, sma, wma} = movingAverages;
