Nodejs/Typescript 錯誤：SyntaxError：意外令牌：

Question

我在名為 spartan.ts 的單獨文件中定義了一個類，它是這樣的：

class Spartan {
    name: string;
    constructor(name: string) {
        this.name = name;
    }
    test() {
        return this.name;
    }
}

module.exports = Spartan;

然后我將其導入其他文件，如下所示：

var Spartan = require("../entities/spartan.ts");
var mySpartan = new Spartan("myName");
console.log(mySpartan.test())

我的 tsconfing.json 看起來像這樣：

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "module": "es2015",
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2017",
      "dom"
    ]
  }
}

然后我得到這個錯誤：

SyntaxError: Unexpected token :
        at createScript (vm.js:80:10)
        at Object.runInThisContext (vm.js:139:10)

您可能應該使用 ES2015 模塊語法進行導入/導出，例如：

export class Spartan {
    name: string;
    constructor(name: string) {
        this.name = name;
    }
    test() {
        return this.name;
    }
  }

進而：

import { Spartan } from "../entities/spartan.ts";
let mySpartan = new Spartan("myName");
console.log(mySpartan.test())
