@krisk is this a known issue. I'm a patreon supporter if that helps :)

Hey! Would you have a sample project I can check? Have you tried just doing import Fuse from 'fuse.js'? Could you also share your tsconfig.json? Thanks!

Thanks Krisk, I created a basic TS CRA example and it seems to be working fine. It's failing in a Ruby on Rails project that uses the webpacker ruby gem so that's probably the issue. We're moving this project out of webpacker pretty soon so we're not worried about it.

I also encouter this problem like below, after I use CRA build my react rpoject, but I don't use typescript. How could I solve this problem ? Thx.
