类型错误：未定义+玩笑+中的NodeJS无法读取属性“原型”

我使用的玩笑中的API的NodeJS的单元测试。我已经安装了玩笑，并在它的package.json添加到脚本以及。但面临的问题：

FAIL API /测试/ math.test.js●测试套件运行失败

下面是我对同一样品类：

math.js：

  const sum = (a, b) => a + b
  const mul = (a, b) => a * b
  const sub = (a, b) => a - b
  const div = (a, b) => a / b

  export default { sum, mul, sub, div };

math.test.js：

 const  {sum, mul, sub, div}  = require("./math")

 test("Adding 1 + 1 equals 2", () => {
   expect(sum(1, 1)).toBe(2)
 })
 test("Multiplying 1 * 1 equals 1", () => {
   expect(mul(1, 1)).toBe(1)
 })
 test("Subtracting 1 - 1 equals 0", () => {
   expect(sub(1, 1)).toBe(0)
 })
 test("Dividing 1 / 1 equals 1", () => {
   expect(div(1, 1)).toBe(1)
 })

任何建议表示赞赏。谢谢！

改变你在math.js出口是：

module.exports = { sum, mul, sub, div };

的NodeJS不支持ES6导入/导出语法，我相信。
