With my node(v16.13.2)

const os = require("os");

this is perfectly work.

But

import os from "os";

This gives me an error that Module 'os' has no default export

I don't understand why it is.

And why node is designed like that.

    Why? Because _"Module 'os' has no default export"_. Use `import * as os from "os"` to import the entire thing or only import what you need, eg `import { arch } from "os"` – Phil May 15 '22 at 04:34

you can fix this by saving the file with .mjs extension instead of .js, or by adding { "type": "module" } to your package.json file
