I have the following in my vimrc:

call plug#begin()
Plug 'https://github.com/vim-scripts/RltvNmbr.vim'
call plug#end()

set number

When I type :so % while in my vimrc, it will turn on the relative line numbers with no error message.

However if I :q and reopen that same vimrc, I get:

E492: Not an editor command: RltvNmbr
Press ENTER or type command to continue

I was under the understanding that opening a file in vim automatically sources the vimrc. Thus I do not understand why I get the above error when opening a file in vim, but not when manually sourcing the vimrc.

    No, plugins are sourced after your init scripts. Check the order in :h startup or check the output of the :scriptnames command. So perhaps you need to use an VimEnter autocommand to call the RltvNmbr command? Jan 21, 2023 at 19:35
  • That's good to know! I did try au VimEnter RltvNmbr but that didn't seem to do anything. I have other plugin-related commands being executed after my call plug#end() and those don't seem to be causing any problems...

    it should be au VimEnter * RltvNmbr Jan 21, 2023 at 19:56
  • That fixed it. Thank you very much stranger! Edit: How come this command failed but other plugin-related commands worked following my call to call plug#end()?

    @brianxk that depends on what those commands were. User commands would suffer the same problem, but calling autoload functions or setting variables probably won’t

1 Answer 1


As Christian Brabandt pointed out, the plugin was being sourced after the vimrc when opening the vimrc from scratch (vs. :so % while the vimrc is still open).




au VimEnter * RltvNmbr

did the trick.
