我正在嘗試進行一個簡單的測驗以了解使用 mocha 的單元測驗。

testA.spec.ts
import * as chai from 'chai'
const expect = chai.expect
describe('First Test', () => {
it('should run the test', () => {
const a = 12
expect(a).to.be.equal(12)
})
})
當我運行時npm test，出現以下錯誤。
/home/user/dev/unitTest/node_modules/@babel/core/src/config/files/index-browser.ts:1 import type { Handler } from "gensync";
^^^^^^語法錯誤：不能在模塊外使用匯入陳述句
嘗試了所有可以在互聯網上搜索的內容，但仍然無法解決這個問題。
uj5u.com熱心網友回復：
我找到了解決方案。在里面package.json我添加了對 mocha的要求：
"devDependencies":{...},
"mocha": {
"require": [
"support/ts-node-register.js"
],
ts-node-register.js
const tsNode = require('ts-node');
tsNode.register({
files: true,
});
