Describe the bug

All installs are following the same error message: tried with both stable and build using yarn

Reproduce the bug

We will close your issue when you don't provide minimal vimrc and we can't reproduce it

• Create file mini.vim with：

I can't reproduce this issue.

vim version: NVIM v0.6.1

I don't know this related or not, try upgrade your nvim and try again.

[eloraiby]

what version do you recommend? according to the doc, it should work:

Neovim >= 0.4.0.

[fannheyward]

Yes, coc should work on nvim 0.4.0+. I'm using 0.8.2. I'll try with 0.6.

[eloraiby]

Thanks, tried version 0.8.2, same issue:

I know it's more work, but you might be able to reproduce it on a clean ubuntu 22.04 with neovim, latest nodejs and npm (downloaded)

[fannheyward]

Tested with nvim 0.6.1, on macOS, still can't reproduce.

[eloraiby]

anything special to env variables you use?

[fannheyward]

Debuging on this.

[fannheyward]

Do you have set g:coc_data_home?

[eloraiby]

Found it! Ubuntu or rather Kubuntu 22.04 doesn't add XDG_CONFIG_HOME env variable, we need to set it manuall to ~/.config

[eloraiby]

Thanks @fannheyward , closing it!

[fannheyward]

What's the output of :echo exists('$XDG_CONFIG_HOME'), :echo $XDG_CONFIG_HOME and :echo len($XDG_CONFIG_HOME)?

Testing before manually set.

[eloraiby]

they were set to .config , changed to /home/redacted/.config and now they work

[fannheyward]

Yes, after you set it to .config coc works as expected.

I want to debug the checking of $XDG_CONFIG_HOME. coc check $XDG_CONFIG_HOME exists but still failed on your env. Looks like $XDG_CONFIG_HOME in your env is exists but set to empty, so please help me to debug this.

1. don't set it to .config 2.:echo exists('$XDG_CONFIG_HOME'), :echo $XDG_CONFIG_HOME and :echo len($XDG_CONFIG_HOME)

[eloraiby]

0, nothing, `0' respectively

[fannheyward]

they were set to .config , changed to /home/redacted/.config and now they work

Got the problem.

if exists('$XDG_CONFIG_HOME')
    let dir = resolve($XDG_CONFIG_HOME."/coc")

$XDG_CONFIG_HOME is set to .config, but incorrect, can't resolve to correct dir.

[eloraiby]

yep
