如何配置rollupJs将nodeJs脚本转换为es6模块？

问题描述

我想配置一个脚本findFruit.js，该脚本在nodeJs下编写，并包装到一个库中，并使其对其他可能由nodeJs或es6代码编写的项目有用。如何从es6模块配置汇总？ 使用

后，我收到错误消息

import * as obj from './application'
^^^^^^
SyntaxError: Cannot use import statement outside a module

//~/application/src/findFruit.js
function findFruit() {
  return 'banana'
}
module.export = findFruit
//~/application/package.json
{
  "name": "get a fruit","version": "0.0.0","description": "test","author": "author","license": "UNLICENSED","main": "dist/findFruit.js","scripts": {

  }
}
//~/application/rollup.config.js
import commonjs from "@rollup/plugin-commonjs";
import pkg from "./package.json";
import autoExternal from "rollup-plugin-auto-external";
export default {
  input: 'src/findFruit.js',plugins: [autoExternal(),commonjs()],output: {
    file: pkg.main,format: 'cjs',exports: 'named',};
//under ~/a.js
import * as obj from './application'
obj(});
//import * as obj from './application'
//^^^^^^

//SyntaxError: Cannot use import statement outside a module

//under ~/a.js
const findFruit = require('./application').default;
console.log(findFruit())
//no problem
