node.js:意外的令牌{

所以我有一个使用typescript为mocha编写的单元测试。 我试着用“咕噜”来运行它(这在这里不起作用)。 我得到以下例外:

(function (exports, require, module, __filename, __dirname) { import { assert } from 'chai';
                                                                     ^

SyntaxError: Unexpected token {
    at new Script (vm.js:74:7)
    at createScript (vm.js:246:10)
    at Object.runInThisContext (vm.js:298:10)
    at Module._compile (internal/modules/cjs/loader.js:657:28)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:700:10)

有人能告诉我在tsconfig.json中需要什么设置来解决这些问题吗?

node -v 
v10.6.0
tsc -v
Version 2.9.2

这是我的tsconfig.json:

{
    "include" : [
        "src",
        "test",
        "unittest"
    ],
