摩卡测试使用打字稿失败

Question

我有一个项目，我正在使用TS和Rollup。我的代码构建并运行正常，但是当我通过npm run test运行测试时，它们会失败并显示SyntaxError: Unexpected token {错误消息。

现在我知道问题在于ES6语法，因为我在我的测试文件中使用import，似乎测试没有被编译但不确定原因。

我的package.json的相关部分：

  "module": "dist/index.es.js",
  "types": "./dist/index.d.ts",

  },

我的test.spec.ts文件：

    import { loginUser } from './loginUser'

    console.log(loginUser)

我的tsconfig文件:(我已经尝试从排除中删除spec文件，但遗憾的是它相同）

{
  "compilerOptions": {
    "target": "es5",                          /* Specify ECMAScript target version: 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017','ES2018' or 'ESNEXT'. */
    "module": "es6",                     /* Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', or 'ESNext'. */

    "skipLibCheck": true,
    "sourceMap": true,
    "moduleResolution": "node"
   },
   "exclude":[
     "node_modules",
     "dist",
     "./**/*.spec.ts",
     "./test/**/*.ts"
   ]
  }

我的rollup.config文件

import typescript from 'rollup-plugin-typescript2'
import replace from 'rollup-plugin-replace'
import pkg from './package.json'
export default {
    input: 'src/index.ts',
    output: [
        {
            file: pkg.main,
            format: 'cjs',
        },
        {
            file: pkg.module,
            format: 'es',
        },
    ],
    external: [
        ...Object.keys(pkg.dependencies || {}),
        ...Object.keys(pkg.peerDependencies || {}),
    ],
    plugins: [
        typescript({
            typescript: require('typescript'),
        }),
        replace({
            'process.browser': !!process.env.BROWSER
        })
    ],
}

你的摩卡设置看起来是正确的。

./node_modules/mocha/bin/mocha --inspect-brk=9230 -r ts-node/register tests/**/*spec.ts"

• 你安装npm i ts-node了吗？
• 您是否认为inspect-brk会在检查员中继续执行之前停止执行？ +还检查端口
