After leaving Neovim I get the following error:

Error detected while processing DirChanged Autocommands for "*":
E475: Invalid argument: Channel doesn't exist
E475: Invalid argument: Channel doesn't exist
Error detected while processing function <SNR>70_nvim_job_exit_wrapper[1]..gutentags#ctags#on_job_exit[1]..gutentags#remove_job_by_data[2]..gutentags#remove_job:
line   22:
E171: Missing :endif

Steps to reproduce

1. open up a file with neovim
2. edit file
3. quit Neovim with :x

Share your setup

• What OS and version of Vim are you using? Catalina 10.14
• What version of ctags, gtags, or whatever do you have installed? latest? It's a fresh install from homebrew
• Are you using g:gutentags_cache_dir? no

Post the logs

• Run :let g:gutentags_trace = 1.
• Reproduce the bug.
• Run :messages and show the messages that Gutentags posted.
• Look for the tags.log file that Gutentags' script left behind, and post its contents.

This is minimal vimrc, I think.

How to reproduce

1. nvim -u /tmp/mini.vim somefile
2. edit
3. save (:wqa)

syntax on
filetype plugin indent on

if has('vim_starting')
  let s:pluin_manager_dir='~/.vim/plugged/vim-plug'
  execute 'set runtimepath+=' . s:pluin_manager_dir
endif
call plug#begin('~/.vim/plugged')
  Plug 'ludovicchabant/vim-gutentags'
  Plug 'neoclide/coc.nvim', {'branch': 'release'}
cal plug#end()

let g:coc_global_extensions = [ 'coc-snippets' ]

FWIW this workaround works for me to stop the failure #178 (comment) this does not fix it entirely but does seem to improve it

[ludovicchabant]

I can't quite reproduce this bug. I have neovim 0.4.4 (from homebrew on macOS), and I had to modify the minimal vimrc since I don't have a plugin manager (just a barebones neovim):

syntax on
filetype plugin indent on

if has('vim_starting')
  execute 'set runtimepath+=~/Code/DotFiles/vim/bundle/gutentags'
  execute 'set runtimepath+=~/Code/Tests/coc.nvim'
endif

let g:coc_global_extensions = [ 'coc-snippets' ]

I don't see any errors so far. It could be because coc is non-functional: it's asking me to install all kinds of javascript stuff to enable itself...

[infokiller]

@ludovicchabant I also can't reliably reproduce this bug. I used to hit it consistently on a repo I worked on some time ago, but I recently re-enabled gutentags (I love it BTW but I had to disable it because of this bug) and I didn't hit the bug again (yet). And I don't use coc at all.

I'm saying this just to emphasize that the bug is real, it's just elusive :)

i also cannot repro it. i try

" File: $XDG_CONFIG_HOME/nvim/test.vim
" OS: linux v5.4.13
" Vi: nvim v0.4.3
" Py: cpython v3.6.10
" Term: guake v3.7.0
syntax on
filetype plugin indent on
set runtimepath=$VIMRUNTIME,$GITHUBWORKSPACE/ludovicchabant/vim-gutentags,$GITHUBWORKSPACE/neoclide/coc.nvim
let g:coc_global_extensions = ['coc-snippets']
" vi -u $XDG_CONFIG_HOME/nvim/test.vim ~/Desktop/test.c

because i don't use vim-plug (but i use coc.nvim)

can i know whether the vim-plug is necessary, please? if so, i'll install a vim-plug to test again.

BTW, i can use the following vimrc to encounter this error.

" File: $XDG_CONFIG_HOME/nvim/test.vim
" OS: linux v5.4.13
" Vi: nvim v0.4.3
" Py: cpython v3.6.10
" Term: guake v3.7.0
set runtimepath=$VIMRUNTIME,$GITHUBWORKSPACE/Freed-Wu/LeaderF,$GITHUBWORKSPACE/ludovicchabant/vim-gutentags
" vi -u $XDG_CONFIG_HOME/nvim/test.vim ~/Desktop/test.c

see #283

can anyone repro it?

[ceuk]

Not sure if this is helpful, but I get this on 3 of my machines: Arch, Ubuntu and MacOS Big Sur. The nvim version doesn't seem to matter as I use nightly on some and stable on others.

I can get it to occur consistently on all three machines by quitting neovim within 5 seconds or so of opening it.

(you don't realise how commonly you do this until you start getting an error every time you do 😂)

[jesseleite]

I've been getting this all the time too. It seems to have started around the time I switched to nvim, but no idea if it's nvim specific 🤔

[meangrape]

I'm seeing this intermittently on different files.

Install a plugin 'airblade/vim-rooter' ,can solved this problem.

Install a plugin 'airblade/vim-rooter' ,can solved this problem.

I can confirm this does not fix my issues. It's happening on some of the files, not on all files.

[sandrodz]

I am experiencing this bug after moving from vim to neovim.

[WilliamDugdale]

I fixed this by running
:healthcheck
from within nvim. This alerted me to the fact that python had an error, so I followed the instruction to:
pip install pynvim
When I ran :healthcheck again, all was well, and on quitting nvim, I have not had the DirChanged error since.

Edit: Further evidence suggests it still throws the error if the file is saved, but doesn't on a non-edit.

Same issue here, rather consistently:

I can reproduce below issue with 2 conditions met.

1. Let nvim to open file out of file the project location.
   ?? Will this step create new tags or do some changes??
2. quit nvim immediately. must use cmd :wq but not :q
   Looks like this step break step1's process, since if i wait to several seconds to let new tags create success, then can't reproduce below error.
