ERR_REQUIRE_ESM with jiti/register

[yshrsmz]

Environment

OS: Mac Sequoia 15.2 Node.js: 20.18.1 Package Manager: [email protected] jiti: 2.4.2 TypeScript: 5.7.2 Fastify: 5.2.0

Reproduction

https://github.com/yshrsmz/jiti-watch-test

Describe the bug

When running Fastify app with node --import jiti/register src/index.ts, it throws an ERR_REQUIRE_ESM error.

I couldn't reproduce the error when I directly used thread-stream(it might be because I didn't fully understand thread-stream), so the repro has a bit big dependency.

Additional context

No response

A simplified minimal reproduction: https://stackblitz.com/edit/github-svycnqv9?file=src%2Findex.js&startScript=dev

Although not the same error in StackBlitz, but it can be reproduced locally as described in this issue.

I have the same issue with an oclif CLI app. It uses ejs, which in turn imports the package version from its package.json file:

var _VERSION_STRING = require('../package.json').version;

which seems like a common pattern to me. This currently crashes JITI:
