Extension unable to find nix-shell

[derrickbeining]

Describe the bug
I can't get the extension to work. It just gives me this error notification:

Command failed: nix-shell /Users/derrickbeining/Dev/ihp-app/default.nix --run env /bin/sh: nix-shell: command not found

If I go into ~/.vscode/extension/arrterian-nix-env-selector-0.1.2/out/helpers.js and replace nix-shell with the absolute path to the binary and restart vscode, then the extension works properly.

Perhaps this is just a problem with my environment, but perhaps if nix-env-selector exposed configuration to be able to specify the path to nix-shell, then that could fix my issue.

To Reproduce
Steps to reproduce the behavior:

1. Fresh install of nix/nix-shell
2. Fresh install of plugin
3. Open project with default.nix expression
4. Open command panel in VS Code and run "Nix-Env: select environment" command
5. See error notification

Expected behavior
I expect the extension to be able to find and run nix-shell on my PATH

• OS: MacOS Catalina 10.15.6

Can you check that your vscode process really has the correct path with nix-shell available? The extension can see all variables that your VSCode process.

Good point BTW.
