Unable to install OCaml on macOS Mac M1

Question

I had installed merlin 6 months ago to be able to compile Ocaml and I had no problems. I have recently upgraded to update everything but it was impossible to make the package work.

When I try to reinstall it I get this error message (opam install -y merlin):

If you ever have an idea to solve this problem I'm interested
