Can't build with webpack

[diogosantosmendes]

I'm trying to build my project with @msgpack/msgpack@2.5.1 and that is not possible (error log bellow),

when I downgrade to version 2.2.1 it works again, do you understand why is that?

I changed my import from "@msgpack/msgpack" to "@msgpack/msgpack/dist" and it worked for me

Thank you for your report. It seems definitely a packaging bug in this module. Will look into it on the weekend.

Same here after upgrading from 2.4.1 to 2.5.1. Replacing import { .... } from "@msgpack/msgpack" with import { .... } from "@msgpack/msgpack/dist" helped indeed.

I’m gonna stay on 2.4.1 for now. Big thanks for volunteering to look into the issue @gfx! 👍

@gfx 🙏

Sorry to be late! Released v2.6.0 that includes the fix by reverting the use of tslib.
