不能使用 jest 在模块 node.js 之外使用 import 语句

Question

I have this in index.js function sum(a, b) => a + b exports = { sum } and in index.spec.js I do

import { sum } from './index.js'

then I got error of SyntaxError: Cannot use import statement outside a module

I'm using node v12, what's the problem here? I don't want to use export defaults because I have more than 1 function inside index.js

Answer 1

Try remove = and change exports to export only.

function sum(a, b) => a + b

export { sum }
