Error ERR_REQUIRE_ESM

[1Map]

I get the following error:

Uncaught Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: C:\MyApp\node_modules\temp-write\index.js

I Use Latest NodeJS: 16.2.0
I Use Latest temp-write: 5.0.0

The problem is:
I had it like:

tmpWrite = require('temp-write')

and changed it to:

import tmpWrite from 'temp-write'

It then gives this error:

'import ... =' can only be used in TypeScript files.ts(8002)
