Error [ERR_INVALID_PROTOCOL]: Protocol 'node:' not supported. Expected 'file:'

[msipinski]

Problem:

Using esm to import module that imports builtin Node modules using 'node:*' URL results with an error:

file:///C:/NodeJsProjects/esm-error-test/some-external-module.mjs:1
Error [ERR_INVALID_PROTOCOL]: Protocol 'node:' not supported. Expected 'file:'
    at file:///C:/NodeJsProjects/esm-error-test/some-external-module.mjs:1
    at Generator.next (<anonymous>)

Import with 'node:*' type URL lies inside external package so I can't replace it. Switching my project from CJS to ESM is probably not possible (I'm creating Electron.js app).

Reproducing:

some-external-module.mjs:

import process from 'node:process'

export default process.platform

package.json:

{
  "dependencies": {
    "esm": "^3.2.25"
  }
}

index.mjs:

import platform from './some-external-module.mjs'

console.log('mjs: ' + platform)

index.cjs:

require = require('esm')(module)
const platform = require('./some-external-module.mjs')

console.log('cjs: ' + platform)

Running node index.mjs gives expected output ("mjs: win32"), but running node index.cjs results in error

• esm version: 3.2.25
• node version: v14.15.3

I'm running into the same issue :(

Can confirm this happens as well.

I am also having the same problem.

Is there any update related to this issues?
I also got this error (while using an import).

And when I use a require, I got this error while using a "sharp" libraries:
Cannot find module 'node:util'

[xeoshow]

Any latest update for this?
I also met the same problem, hope esm could support it.
