Nushell+helix - $env.EDITOR does not work from e.g. yazi or git

[rykugur]

I use nushell as my shell, and have recently decided to give helix a try for a month. I've run into a weird issue, and I'm not sure where the problem lies.

Context

Host: Macbook Pro (M2 Pro) 14.7.1 Sonoma
Helix version: helix 25.01.1 (e7ac2fcd)
Nushell version: 0.101.0

Helix and nushell installed from nixpkgs (nix-darwin).

The problem

This morning when I went to do a git pull - I got this error when git was prompting me with an editor to edit/save my merge commit message:

hint: Waiting for your editor to close the file... error: cannot run hx: No such file or directory
error: unable to start editor 'hx'

Additionally, if I try to open a text file in yazi, I get this error:

/Users/rykugur/.dotfiles/flake.nix: line 1: hx: command not found
/Users/rykugur/.dotfiles/flake.nix: line 1: hx: command not found
/Users/rykugur/.dotfiles/README.md: line 1: hx: command not found
/Users/rykugur/.dotfiles/README.md: line 1: hx: command not found

hx is definitely on my path:

~
❯ : which -a hx | to text
command: hx
path: /Users/rykugur/.nix-profile/bin/hx
type: external

and I can launch/use hx normally.

I also have hx exported as my EDITOR:

$env.EDITOR = "hx"

and can run evaluate it, e.g. this works: ^($env.EDITOR) README.md will open README.md in helix without issue.

Does anybody have any thoughts/has experienced this before?

EDIT:

Things work fine if I use nvim e.g.: EDITOR=nvim sops nixos/secrets.yaml

EDIT2:

I tested this out on my desktop PC (running nixOS) and everything appears fine. Seems to be some strange interplay between macOS/nushell/helix.
