错误 [ERR_REQUIRE_ESM]: 运行脚本时必须使用 import 加载 ES 模块

问题描述

我正在尝试测试 imagemin 和 imagemin-mozjpeg，因此我编写了一个小项目来这样做。

index.ts

import imagemin from 'imagemin';
import imageminMozjpeg from 'imagemin-mozjpeg';

(async () => {
  const files = await imagemin(["your-image.jpg"],{
    destination: "compressed-images",plugins: [
      imageminMozjpeg({quality: 50})
    ]
  });
  console.log(JSON.stringify(files,null,1));
})();

ma​​in.ts

require = require('esm')(module/*,options*/);
module.exports = require('./index');

Package.json

}


}

我跑：

yarn run build
yarn run start

并得到以下错误：

$ node ./dist/main.js
/testing-project/node_modules/imagemin/index.js:1
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /testing-project/node_modules/imagemin/index.js
require() of ES modules is not supported.
require() of /testing-project/node_modules/imagemin/index.js from /testing-project/dist/index.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename /testing-project/node_modules/imagemin/index.js to end in .cjs,change the requiring code to use import(),or remove "type": "module" from /testing-project/node_modules/imagemin/package.json.

请告诉我如何解决这个问题，谢谢。

解决方法

问题是各种打字稿配置的混合。启动了一个新项目并解决了问题。
