dune build - Error: Too many opam files for package

[roddyyaga]

After doing opam monorepo lock, opam monorepo pull and dune build for a project, I got this error:

Error: Too many opam files for package "fix":
- duniverse/menhir/fix/fix.opam
- duniverse/fix/fix.opam

Relevant versions lines of the lock file are "fix" {= "20201120"} and "menhir" {= "20201216"}. Is there a way to avoid this?

I experienced the same issue

https://gitlab.inria.fr/fpottier/menhir/-/commit/23391fea326478ae1c49b2f487cd44e1e1dd1593

I cloned this commit and pinned locally and everything worked

Yes, that's because menhir itself vendors fix. opam-monorepo does not know about this. There's little it can do, but in the meantime a recent version will work.

This should be worked around by #367
