upgrade to v1 start with error: cannot find module 'ix/asynciterable/index.js

[zhex900]

I am using v9.12.6

But when I change it to v1 I get this error. Why is that? Compiler config issue?

What do you mean v9.12.6?

Could you please provide a minimum code with reproducible steps for generating your error?
