无法使用TypeScript和包运行Testbed。错误: planck.testbed不是一个函数

Question

是否可以在包中使用Testbed？我在Sandbox上的TypeScript中做了一个简单的例子：https://codesandbox.io/s/planckjs-testbed-ts-n4imh4?file=/src/index.ts，我有一个错误：planck.testbed is not a function

import * as planck from "planck-js";

planck.testbed(function (t)
{
    // Create a world
    const world = planck.World();

    console.log(world.getGravity());

    // Make sure you return the world
    return world;
});

package.json

{
  "name": "testbed-ts",
  "version": "1.0.0",
  "description": "",
  "main": "public/js/bundle.js",
  "targets": {
    "main": {
       "includeNodeModules": true
    }
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "del_files": "del /f /q /s .\\public\\js\\*.*",
    "dev": "npm run del_files && parcel watch src/main.ts"
  },

  }
}

Answer 1

import * as planck from "./node_modules/planck-js/dist/planck-with-testbed";

而不是：

import * as planck from "planck-js";
