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.

Issues like this (e.g., the server binary cannot be found) usually have to do with incorrectly configured shell environment. This is sometimes also caused from using nvm.

I'm unable to test with the current reason-cli and bs-platform for awhile probably. It might be a good idea to open an issue about this on the reason or bucklescript repo or perhaps see if someone on the discord server can help.

Thanks @freebroccolo for the help... maybe it has something to do with my use of asdf for nodejs version management but it's weird since before upgrading reason-cli and bs-platform it worked great for months. So I could keep working I've been testing jaredly's RLS (which is working) and it seems like this is an isolated problem for me so I will close.

For what it's worth I'm running into this as well, also after upgrading reason-cli. It looks like the latest version of reason-cli simply doesn't include ocamlmerlin-server anymore:

❯ ls /Users/Pascal/.asdf/installs/nodejs/8.9.1/.npm/lib/node_modules/reason-cli/bin
_storePath         ocamlmerlin-reason refmt              rtop
ocamlmerlin        reactjs_jsx_ppx_v2 refmttype          utop

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 🚀 reasonml/reason-cli#87
