尝试以可视代码导入模块时，其显示意外令牌{

Question

您好，我正在使用可视代码来运行项目，这是我的代码

external.js

 export let keyValue=1000;

script.js

import {keyValue} from './external.js';
console.log(keyValue);

然后我有命令将文件作为节点脚本运行

然后当我在可视代码中运行节点脚本时，它显示以下错误

F:\es6-examples\modules-classes\script.js:1

  (function (exports, require, module, __filename, __dirname) { import 
  {keyValue} from './external.js';
                                                                 ^

SyntaxError: Unexpected token {

它是语法错误问题。尝试此代码

(function (exports, require, module, __filename, __dirname) {import 
    {keyValue} from './external.js';
})
