Cannot install plugin with luarocks

[rajayonin]

It gives the following error when installing:

Error: No results matching query were found for Lua 5.1.
To check if it is available for other Lua versions, use --check-lua-versions

• lua -v: Lua 5.4.8 Copyright (C) 1994-2025 Lua.org, PUC-Rio
• luarocks --version: /usr/bin/luarocks 3.12.2

Minimal init.lua to reproduce this issue (save as repro.lua and run with nvim -u repro.lua):

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
  spec = {
    { "cosmicboots/system-theme.nvim" }
  },
})

It looks like I just fumbled the lua version specifier in the rockspec, so it doesn't handle new minor releases.
Right now it's locked to version 5.1 (lua == 5.1) but it should be at least 5.1 (lua >= 5.1).

Unfortunately, I won't be at a machine I can properly test this on till next week. I can take a look then.

It seems that luarocks only works in Neovim with Lua v5.1, as mentioned in folke/lazy.nvim#1570. I have installed that version, and lazy.nvim says it's all good:

(running :checkhealth)

luarocks
- checking `luarocks` installation
- you have some plugins that require `luarocks`:
    * `system-theme.nvim`
- ✅ OK {luarocks} `/usr/bin/luarocks 3.12.2`
- ✅ OK {lua5.1} `Lua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio`

...but it still doesn't install, probably because that version of Lua is deprecated.

Nevertheless, the "new cool thing" seems to be rocks.nvim... but its own README states that:

rocks.nvim will be undergoing a major rewrite soon. If you're considering switching from another plugin manager and you'd like to avoid churn, we recommend you wait for rocks.nvim v3.0.0.

BTW, already tried the >= thing, it doesn't work.

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
	spec = {
		{ "rajayonin/system-theme.nvim", branch = "fix-rockspec" },
	},
})

@rajayonin that actually makes sense. Neovim bundles Lua 5.1 using LuaJIT, which doesn't support any higher Lua version. When I get a chance, I'll check on the installation issue and see what's going on.

Sorry for the late followup, it seems like there might have been a change with the package manifests on luarocks.
lazy.nvim builds the rockspec with dev manifests (--dev flag), which apparently don't contain dbus_proxy anymore.
