Same exact thing has been happening to me for a week and driving me insane trying to debug

Nvim version:

$ nvim --version
NVIM v0.8.0-1210-gd367ed9b2
Build type: Release

My minimal config with formatting as original poster does.

-- this template is borrowed from nvim-lspconfig
local on_windows = vim.loop.os_uname().version:match("Windows")

local function join_paths(...)
    local path_sep = on_windows and "\\" or "/"
    local result = table.concat({ ... }, path_sep)
    return result
end

vim.g.loaded_remote_plugins = ""
vim.cmd([[set runtimepath=$VIMRUNTIME]])

local temp_dir = vim.loop.os_getenv("TEMP") or "/tmp"

vim.cmd("set packpath=" .. join_paths(temp_dir, "nvim", "site"))

local package_root = join_paths(temp_dir, "nvim", "site", "pack")
local install_path = join_paths(package_root, "packer", "start", "packer.nvim")
local compile_path = join_paths(install_path, "plugin", "packer_compiled.lua")

local null_ls_config = function()
    local null_ls = require("null-ls")
    -- add only what you need to reproduce your issue

null_ls.setup({
  debug = false,
  sources = {
    null_ls.builtins.formatting.prettier.with({
      extra_filetypes = { "toml", "json", "tsx", "tsx", "jsx", "js" },
      extra_args = { "--single-quote", "--jsx-single-quote" },
    }),
    null_ls.builtins.formatting.black.with({ extra_args = { "--line-length", "79" } }),
    null_ls.builtins.formatting.stylua,
    null_ls.builtins.formatting.eslint,
    --null_ls.diagnostics.flake8,
  },
})
end

local function load_plugins()
    -- only add other plugins if they are necessary to reproduce the issue
    require("packer").startup({
        {
            "wbthomason/packer.nvim",
            {
                "jose-elias-alvarez/null-ls.nvim",
                requires = { "nvim-lua/plenary.nvim" },
                config = null_ls_config,

        config = {
            package_root = package_root,
            compile_path = compile_path,
        },
    })
end

if vim.fn.isdirectory(install_path) == 0 then
    vim.fn.system({ "git", "clone", "https://github.com/wbthomason/packer.nvim", install_path })
    load_plugins()
    require("packer").sync()
else
    load_plugins()
    require("packer").sync()
end

#1103

[brymon68]

Hey @jose-elias-alvarez, I appreciate your work and thank you for the link to the closed PR.

Can you provide some guidance as to how you validate this fix? Because I am running the most recent build for neovim:
NVIM v0.8.0-1210-gd367ed9b2

$ /usr/local/bin/nvim --version
NVIM v0.8.0-1210-gd367ed9b2
Build type: Release
LuaJIT 2.1.0-beta3
Compiled by runner@Mac-1664551586262.local

And I am still having this issue with the above minimal config I pasted above. Is there something I am perhaps doing wrong? Apologies, but I am relatively new to neovim

[ThanhDat-Vo]

@brymon68
I temporarily fix by installing a commit
use({ "jose-elias-alvarez/null-ls.nvim", compile = "76d0573fc159839a9c4e62a0ac4f1046845cdd50" })

[jose-elias-alvarez]

The error is caused by an incompatibility in your runtime files. If you are running or ever were running a dev version of Neovim, then you need to make sure that your runtime files match the version of Neovim you are currently running. This is automatically handled by the make install step listed on the Neovim wiki, but for some reason a lot of users skip this.

I don't know how you installed Neovim in the first place, but the gist of the issue is that you have old runtime files on your system, and you need to delete them.

[brymon68]

Thanks @jose-elias-alvarez - That was helpful. Turns out I had a few artifiacts lying around in /usr/local/bin/. Sort of wish the neovim docs had something about where to place the binary, and other artifacts when you download. Perhaps that is an opportunity for me to contribute :)

Thanks again
