bug: checkhealth problem

[luxcih]

Did you check docs and existing issues?

• I have read all the lazy.nvim docs
• I have searched the existing issues of lazy.nvim
• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

v0.9.5

Operating system/version

Arch Linux 6.8.5

Describe the bug

Like #1371, #1374, and #1405:

lazy: require("lazy.health").check()

- ERROR Failed to run healthcheck for "lazy" plugin. Exception:
  function health#check, line 25
  Vim(eval):E5108: Error executing lua ...cih/.local/share/nvim/lazy/lazy.nvim/lua/lazy/health.lua:29: attempt to index field 'uv' (a nil value)
  stack traceback:
  ...cih/.local/share/nvim/lazy/lazy.nvim/lua/lazy/health.lua:29: in function 'check'
  [string "luaeval()"]:1: in main chunk

This is a :checkhealth problem for lazy.nvim, because when you just bootstrap/install lazy.nvim and not require("lazy") after, it will give an error on :checkhealth unlike the older versions (v10.17.0 and below). This bug is not really a big deal, I know, but this bug wasted my time debugging my Neovim configuration just because I didn't add require("lazy") after bootstraping, and I don't want others to experience the same thing here.

#1374 (comment)

Steps To Reproduce

1. Bootstrap lazy.nvim (v10.18.0 or above), don't add require("lazy")
2. Run :checkhealth

Expected Behavior

:checkhealth works fine without any errors.

Repro

-- Define lazy.nvim installation path
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"

-- Ensure that lazy.nvim is installed
if not (vim.uv or vim.loop).fs_stat(lazypath) then
    print("Installing lazy.nvim")
    vim.fn.system({
        "git",
        "clone",
        "--filter=blob:none",
        "https://github.com/folke/lazy.nvim.git",
        "--branch=stable", -- latest stable release
        lazypath,
    })
end

-- Add lazy.nvim to runtime path
vim.opt.rtp:prepend(lazypath)

-- Without this, it gives an error on :checkhealth
-- require("lazy")
