javascript - 导出未定义为 ia tsc'ed (js) 文件

Question

我对 typescript 比较陌生，我很不明白为什么在执行 tsc Program.ts 之后然后运行

Program.js在浏览器中它对我大喊大叫 ReferenceError: exports is not defined

程序.ts

import { TestClass } from './TestClass';

var tc = new TestClass();

console.log(tc.Test("test"));

测试类.ts

import {Data} from "./Data";

export class TestClass
{
    constructor() {}

    Test(originalString:string)
    {
        console.log(Data.Symbols["John"] + " " + originalString);
    }
}

数据.ts

export abstract class Data
{
    public static Symbols:{[symbol: string] : string} = 
    {
        "John":"a5fq36831v",
    }
}

包锁.json

{
  "requires": true,
  "lockfileVersion": 1,
  "dependencies":
  {
    "uniq": 
    {
      "version": "1.0.1",
      "resolved": "https://registry.npmjs.org/uniq/-/uniq-1.0.1.tgz",
      "integrity": "sha1-sxxa6CVIRKOoKBVBzisEuGWnNP8="
    }
  }
}

我有 npm i @types/node安装

我看过这个帖子:Typescript ReferenceError: exports is not defined

但我没有tsconfig.json或 babelrc文件。

这个技巧部分对我有用 <script>var exports = {};</script>

因为之后ReferenceError: require is not defined

是否可以在不安装额外大量软件的情况下使其工作？

npm i common-js

npm WARN saveError ENOENT: no such file or directory, open 'C:\Repo\Master\src\TypeScript\package.json'
npm WARN saveError EPERM: operation not permitted, rename 'C:\Repo\Master\src\TypeScript\package-lock.json.1161578677' -> 'C:\Repo\src\TypeScript\package-lock.json'
npm WARN enoent ENOENT: no such file or directory, open 'C:\Repo\Master\src\TypeScript\package.json'
npm WARN TypeScript No description
npm WARN TypeScript No repository field.
npm WARN TypeScript No README data

+ common-js@0.3.8
added 1 package in 2.141s
PS C:\Repo\Master\src\TypeScript> tsc ProgramParser.ts

ReferenceError: exports is not defined Program.js:2:1
ReferenceError: Parser is not defined html.html:40:6

需要检查环境中是否安装了commonjs。
