Broken when using Lua5.1

[mirachan010]

Description

Can't move in aarch64(RaspberryPi4-8GB) neovim from apt. This neovim is use Lua5.1 not LuaJIT.

Expected Behavior

in use :Telescope <TAB> give some completion.

Actual Behavior

echo some error

:Telescope ...

We still have some jit stuff in plenary.path. I will remove them as soon as possible and make sure Lua 5.1 works. But it will not work as good as the jit version. We need it for some ffi stuff. E.g. we no longer can shorten the path without jit: https://github.com/nvim-telescope/telescope.nvim/blob/993e383dd5356bf10c5cf2b5d0ac88f9c7746181/lua/telescope/path.lua#L23-L45

So i highly suggest you build Neovim with luajit.

I will edit the title. Its not really broken for this platform, it works on my raspberry pi 4.

Does this still happen? I have removed the jit part in plenary.path :) I haven't build neovim with lua5.1 yet

It has other error.

I can't install and build lua jit version https://github.com/neovim/neovim/issues/13760

After switching to vim-plug from bundle this error stopped popping up. Per the information on this issue this is what fixed it for me

brew install luajit brew reinstall neovim

@Conni2461 Is this still a thing you are working on? There some architectures out there that doesn't support LuaJIT and therefore use Lua 5.1. Mainly because the LuaJIT maintainer blocks PR's. The neovim team sadly doesn't want to replace luajit with luajit2 upstream.
