I think you should drop the useTsNode option from your package.json, that option triggers the ts-node.register() which you don't need with bun. Instead, you need the new alwaysAllowTs option, which will make the ORM respect the TS files, but as opposed to the useTsNode it won't trigger the ts-node.register() call.

@B4nan with pnpm also not work

[notramo]

Is this issue still relevant?
commitlint works in Bun 1.0.14, which was previously crashing because of this bug.

[Jarred-Sumner]

@paperdave fixed this some time ago

[notramo]

@Jarred-Sumner I checked it again, and commitlint crashes if the node_modules were installed by pnpm (but works if it was installed by Bun). Since the Bun built-in package manager is highly unusable for complex scenarios (e.g. workspaces), it's very likely that some projects use pnpm for package management, and Bun for everything else.

[paperdave]

this issue is not fixed as of 1.0.14. the work seems to be started on pr here: #6188. i did not have time to finish it up at the time, and i am now focusing on the windows build. someone else will have to pickup implementing the node:module internal apis.

Getting this error with macOS arm64, Bun v1.1.17 and threads.js v1.7.0 when setting up a pool with thread.js.

Error

Setup

// index.ts
import { spawn, Pool, Worker } from "threads";

const pool = Pool(
  () => spawn(new Worker("./workers/add")),
  8
);

// workers/add.ts
import { expose } from "threads/worker"

expose(function add(a, b) {
  return a + b
})

[Jarred-Sumner]

Confirming this is not fixed, and also probably very easy to implement.
