TypeError: g is not a constructor

Just npm installed the latest version and tried running the extract user streaming example (https://github.com/instructor-ai/instructor-js/blob/99af6d1c8135b5e0be80dbbaddcf9e2cffd5230d/examples/extract_user_stream/index.ts). Got this very cryptic error:

Could use some help...and source maps ha.

[roodboi]

can you share a reproducible example?

threw up a bare-bones test here - been unable to repro myself

https://github.com/hack-dance/instructor-stream-test/tree/main

[rgarcia]

I'm using tsx, not bun. I was able to repro it in your repo by running

npm install --save-dev tsx
npm run tsx index.ts

The bun way works for me though so I'll just use that

[roodboi]

ok so - bun should just work - but I dug in a little and tested with both ts-node and TSX - they both have problems figuring out how to resolve es modules further upstream for some reason - I updated those upstream deps to include exports and was a bit more explicit and it now seems to work fine with whatever ts-node, TSX, bun, build + node, whatever

also updating this package to be a bit more explicit as well so we don't run into anything like this again.

Thanks for making the issue!
