Did you check docs and existing issues?

0.10

Operating system/version

MacOs

Describe the bug

When i do a LazyHealth check wihtin lazyvim it says that luarocks is installed but the version is not correct. Looking at the website of luarocks they are even using luarock with lua 5.3.

Steps To Reproduce

Install the latest version of lua
Install luarocks
LazyHealth

Expected Behavior

It should not give a warning as I'm using a newer version of lua

Repro

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here

luarocks for NEovim plugins requires Lua 5.1, that is completely correct.

I've improved the health check to show steps you can do to fix your luarocks installation.

luarocks for NEovim plugins requires Lua 5.1, that is completely correct.

oh! ok thank you! I wanted to create the ticket more of a question as I wasn't sure.

@folke thanks for a lot of your plugins!
I have a question, since Lazy supports now luarocks and especially on macOS with Homebrew, lua@5.1 is deprecated and needs workaround to work with newer version,
isn't enough luarocks --lua-version=5.1 even with newer version of Lua as you’re already using ?

Yes, you need 5.1. This is the last time I'll answer this question.

[folke]

As is explained in the healthcheck, you can just enable hererocks instead

In case it's helpful to anyone, mise can be used to install lua 5.1 (with luarocks):

mise plugins add lua
mise use -g lua@5.1

after which luarocks should be available from ~/.local/share/mise/installs/lua/5.1/luarocks/bin/luarocks and :checkhealth in neovim won't show any errors or warnings about luarocks.

5.1 is on nix as well, if that's more your thing:

nix profile install nixpkgs#lua51Packages.lua
nix profile install nixpkgs#lua51Packages.luarocks
