Bug Reproduction GitHub Repo

Expected behavior

Syncpack succeeds with

✓ No issues found

Actual behavior

Syncpack throws the following error:

 ✗ Node.js/npx/tsx process failed with stderr: error: Cannot find module './cjs/index.cjs' from ''

 Bun v1.3.2 (Linux arm64)

Contents of syncpack configuration file

export default {
    indent: "    ",
} satisfies import("syncpack").RcFile;

Optional comments

The bunx syncpack lint runs successfully if you add a .syncpackrc.json file to the root of the project.

For example, with the following content:

{
  "$schema": "./node_modules/syncpack/dist/schema.json",
  "indent": "    "
}

I think this could be a bug with tsx:

root@40ae063a4ab3:/workspaces/syncpack-alpha-devcontainer-bug# node index.ts
Hello World!
root@40ae063a4ab3:/workspaces/syncpack-alpha-devcontainer-bug# bun index.ts
Hello World!
root@40ae063a4ab3:/workspaces/syncpack-alpha-devcontainer-bug# node_modules/.bin/tsx index.ts
error: Cannot find module './cjs/index.cjs' from ''

Bun v1.3.5 (Linux x64 baseline)

I've been looking for an hour or two though and haven't found a fix yet. As you mention though, this problem only happens when syncpack is trying to run a TypeScript or JavaScript config file. I'll revisit this one.
