Unbound module error

[bayweiheng]

Hi, first of all, thanks so much for this wonderful tool! I'm just starting out in OCaml and don't know my way around vim/emacs so this has been really useful for me.

I'm probably just being dumb, but why do I get Unbound module Async error when I use merlin with "PKG core async lwt" directive in my .merlin file (same problem with cryptokit etc., but the programs do compile, so I definitely have the modules installed - used OPAM)? open Core works fine with the unbound module error.

Is thee anything I can do to enable autocomplete/disable such warnings for the Async module? I've scoured online (both this page and the ocaml one)to no avail, would greatly appreciate your kind help. Thanks!

Is it possible that you have multiple versions of Merlin installed?
