TypeScript + NodeJS控制台命令行应用，如何做到index.ts适配有ES6模块或者无ES模块

tsconfig.json 用umd打包方法

头两行可以选择注释掉就是无模块。用umd都可以顺利编译、运行

import { myutil } from "./myutil";

myutil.exportIt();

let now = new Date(Date.now() + 8 * 60 * 60 * 1000);
let time = now.toISOString();
time = time.substring(0, time.length - 5);
time = time.replace("T", " ");
console.log(time);

tsconfig.json

    "compilerOptions": {
        "target": "es5",

        "outDir": "./js",
