Problem description

After installing the mason.nvim plugin, no LSP server relying on NPM could not be installed even though both Node and Npm executables can be found in %PATH%:

﬌ node -v v18.12.1

﬌ npm -v 8.19.2

﬌ Get-Command npm

CommandType Name Version Source

---

Application npm.exe 0.0.0.0 XXX\volta\current\appdata\bin\npm.exe

I used scoop to install volta, and then installed node/npm through volta.

After checking Issue #781, it seems that mason only checks the npm executable through npm.cmd or npm and does not consider npm.exe as a valid candidate (volta installed only .exe files, no .cmd nor .ps1).

I updated the spawn.lua file as below:

---@alias JobSpawn table<string, async fun(opts: SpawnArgs): Result>
---@type JobSpawn
local spawn = {
    _aliases = {
        npm = platform.is.win and "npm.exe" or "npm.cmd" or "npm",
        gem = platform.is.win and "gem.cmd" or "gem",
        composer = platform.is.win and "composer.bat" or "composer",
        gradlew = platform.is.win and "gradlew.bat" or "gradlew",
        -- for hererocks installations
        luarocks = (platform.is.win and vim.fn.executable "luarocks.bat" == 1) and "luarocks.bat" or "luarocks",
        rebar3 = platform.is.win and "rebar3.cmd" or "rebar3",
    },
    _flatten_cmd_args = _.compose(_.filter(_.complement(_.equals(vim.NIL))), _.flatten),
} 

and managed to get npm.exe recognized by mason:

Can't we just add an option to specify the executable via the setup function? I'm also having problems getting mason to detect my pyenv-win path under MSYS2. neovim/neovim#21175 doesn't help either, because it only works if your shell is pwsh or cmd. I'm currently using this hack, which works for for python:

vim.g.python3_host_prog = "python.bat"

I also would like the ability to specify the executable paths if possible. I use lazy loading for loading npm/nvm/node and even though I can run npm at the command line, Mason isn't able to detect that it's there.

I have a similar issue when attempting to install the typescript lsp, though in my case it seems to fail to resolve node
