Hi tried to install chalk on my very simple app and then i got error:

Error [ERR_REQUIRE_ESM]: require() of ES Module my-file-is-here  and chalk\node_modules\chalk\source\index.js from my-file-is-here not supported.
Instead change the require of index.js in my-file-is-here to a dynamic import() which is available in all CommonJS modules.
    at Object.<anonymous> (`my-file-is-here`) {
  code: 'ERR_REQUIRE_ESM'
}

thats my code:

const os = require("os")
const chalk = require("chalk")

console.log("app running")
chalk node.js

Chalk 5 has changed to ESM. They provide a link to better understand what that means: Pure ESM.

From chalk README:

IMPORTANT: Chalk 5 is ESM. If you want to use Chalk with TypeScript or a build tool, you will probably want to use Chalk 4 for now.

As of this reply, the last version of chalk 4 is 4.1.2.

That is something to do with the version you are using which is I think 5.0.0. Use chalk@4.1.2 instead

  1. npm uninstall chalk

then

  1. npm i chalk@4.1.2

now you can run your code

const chalk = require('chalk');
console.log(chalk.blue('Hello world!'));

Step-1 npm uninstall chalk (delete all chalk files)

Step-2 npm install chalk@4.1.0

const chalk = require("chalk");
console.log(chalkl.green("Hello"));

Done

You can use dynamic import with chalk^5 ESM in CJS

async function chalk() {
  return (await import("chalk")).default;
}

async function main(){
  console.log((await chalk()).gray(">", ...commands));
}

I simply used import chalk from "chalk" and added "type": "module" in the package.json file which enabled es6 module worked for me quite well.

Think it's ES module and works in import way, but you can do something like this:

const { chalk } = require("chalk");

It worked for me when I worked with firebase in v8 style.

  • Add "type": "module" to your package.json.
  • Replace "main": "index.js" with "exports": "./index.js" in your package.json.
  • Update the "engines" field in package.json to Node.js 12: "node": "^12.20.0 || ^14.13.1 || >=16.0.0".
  • Remove 'use strict'; from all JavaScript files.
  • Replace all require()/module.export with import/export.

Use only full relative file paths for imports: import x from '.'; → import x from './index.js';.

If you have a TypeScript type definition (for example index.d.ts), update it to use ESM imports/exports.

Optional but recommended, use the node: protocol for imports.

//First Change in you Package.json

"main": "app.js",
"type": "module",//use this line

//Second change in App.js

import os from 'os' //  const os = require("os")

import chalk from 'chalk';//const chalk = require("chalk")
