Typescript Angular：7.2.1 ES6 类 ReferenceError：初始化前无法访问X

我正在上下面的打字课

export class Vehicule extends TrackableEntity {
  vehiculeId: number;
  constructor() {
    super();
    return super.proxify(this);
  }
}

我在tsconfig中的typescript目标.json配置为es6:

"compilerOptions": {
    "module": "es2015",
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es6",
}

在运行时，在Chrome中，代码失败:

ReferenceError: Cannot access 'Vehicule' before initialization

我需要把es5改成es6来解决this other problem题.

编辑:

import { Vehicule } from "./Vehicule";

编辑2:我想说这可能与网页包有关，即在genrated模块中导出/导入模块的方式.

编辑3:经过进一步研究，这似乎与上面显示的代码无关.开始一个关于webpack and ES6的新问题.
