execvp(ocamlmerlin-server) (no such file) error since upgrading to reason 3.3.3/bs-platform 4.0.5

MacOS v10.13.6

Everything has been working great for months until I upgraded bs-platform to v4.0.5 (both globally and in-project) and reason-cli (globally) to 3.3.3-macos.

Now when I try to open any .re file the extension throws an error:

ocamlmerlin error: execvp(ocamlmerlin-server): No such file or directory merlin path: /Users/tepple/.asdf/installs/nodejs/10.8.0/.npm/lib/node_modules/reason-cli/bin/ocamlmerlin-server socket path: /var/folders/gs/klj2134gn/T//<not computed yet>

I looked in that referenced directory and the ocamlmerlin executable does exist… just like it did before. If I run ./ocamlmerlin directly in that directory I get the same error message:

tepple@tme-imac-2014: bin (master)$ ./ocamlmerlin
execvp(ocamlmerlin-server): No such file or directory
merlin path: /Users/tepple/.asdf/installs/nodejs/10.8.0/.npm/lib/node_modules/reason-cli/bin/ocamlmerlin-server
socket path: /var/folders/gs/6v085qc96nn_hd5tmq3nzgc80000gn/T//<not computed yet>

This might actually be an issue with https://github.com/reasonml/reason-cli since I have an older version in another directory which when I run ./ocamlmerlin it works.

Ok looks like the binary was always called ocamlmerlin, but that binary seems to be broken in the latest reason-cli (3.3.3-macos). The binary from the previous version (3.3.2-macos-betabeta) is working. I’ll open an issue with reason-cli.

Issue was confirmed in reason-cli and a fix was merged the master already 🚀 https://github.com/reasonml/reason-cli/issues/87
