节点-意外标识符 [英] Node - unexpected identifier

问题描述

我正在尝试使用Node和一些ES6/功能性的东西.
这是两个文件.
dog.js

I'm trying to play around with Node and some ES6/functional stuff.
Here is two files.
dog.js

const dog = () => {
    return {
        test: (arg) => console.log("dog say: " + arg)
    }
}

export default dog;

1.js

import dog from './dog';

const d = dog()
d.test('111');

节点版本-10.4.0(可以使用节点设置)
当我运行node 1.js时-出现错误 Unexpected identifier ，指向了dog.怎么了?

Node version - 10.4.0 (Node settings are fine)
When I'm running node 1.js - getting error Unexpected identifier, pointing on dog. What is wrong here?

P.S..1.js已更新，可正确使用导入的功能，但即使在此之后，我仍然遇到错误.

P.S. 1.js was updated for proper usage of imported function, but even after that I'm still getting errors.

推荐答案

您的代码有效，它记录:

Your code works, it logs:

狗说:111

dog say: 111

但是，ECMAScript模块在实验中节点v10.4.0.

However, ECMAScript Modules are Experimental in node v10.4.0.

您需要使用--experimental-modules标志/选项运行节点.例如

You'll need to run node with the --experimental-modules flag/option. For example

node --experimental-modules 1.js 

另请参阅有关模块文件.mjs扩展名的注释.因此，您可能需要将1.js更改为:

Also see the note regarding .mjs extension for module file(s). So you'll probably need to change 1.js to:

// Note the .mjs extension
import dog from './dog.mjs';

const d = dog()
d.test('111');
