运行 mocha Unittest 时打字稿意外标记“导出”

如何解决运行 mocha Unittest 时打字稿意外标记“导出”

我正在使用 node v15.14.0 通过 typescript 运行 mocha

并使用以下 tsconfig.json

{
  "compilerOptions": {
    "target": "es5",// other attributes
}

我的文件夹结构如下 ./test/test.ts

有以下内容

  import {
        TestState,} from '../lib';

describe('Check my function',() => {

    it('should load testState',() => {
        // check testState 
    });

});

在../lib/teststate.ts里面是下面的代码

export type TestState= {
  value: number;
};

我跑的地方

mocha -r ts-node/register src/test/*.ts 

我收到以下错误：

   export {};
    ^^^^^^
    
    SyntaxError: Unexpected token 'export'

如何导入“TestState”并使用 mocha 进行测试？
