Since commit 4145f5 I am getting "Error running" when running Rg, Buffers and maybe other commands

[nickjj]

• [x] I have fzf 0.22.0 or above
• [x] I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
• [x] I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
• [x] I have read through the manual page of fzf (man fzf)
• [x] I have searched through the existing issues

Hi,

The error happens when using:

• fzf.vim from September 10th 2020
• fzf from October 5th 2020
• Vim 8.1 on Ubuntu 20.04 LTS within WSL 2

Edit: After a bit of debugging I was able to pin point it down to commit 4145f53f3d343c389ff974b1f1a68eeb39fba18b. If I use any commit before that one then everything works without issues.

Everything was working great for a long time but about a week ago I ran a :PlugUpdate after having not run it for months and now every time I run :Rg foo this error pops up instead of returning the search results:

Error running '/home/nick/.fzf/bin/fzf' '--color=bg+:#f0f0f0,bg:#fafafa,spinner:#a626a4,hl:#a0a1a7,fg:#494b53,header:#a0a1a7,info:#c18401,pointer:#a626a4,marker:#e45649,fg+:#494b53,prompt:#a626a4,hl+:#a626a4' '--ansi' '--prompt' 'Rg> ' '--multi' '--bind' 'alt-a:select-all,alt-d:deselect-all' '--delimiter' ':' '--preview-window' '+{2}-5' '--color' 'hl:4,hl+:12' '-

I have a bit of custom fzf related configuration in my vimrc file but the same error happens even if I remove all of my custom configuration, but here's my custom config for reference since it ties back to the exact error above:

let $FZF_DEFAULT_OPTS = '--bind ctrl-a:select-all'

" Customize fzf colors to match your color scheme.
let g:fzf_colors =
\ { 'fg':      ['fg', 'Normal'],
  \ 'bg':      ['bg', 'Normal'],
  \ 'hl':      ['fg', 'Comment'],
  \ 'fg+':     ['fg', 'CursorLine', 'CursorColumn', 'Normal'],

let g:fzf_action = {
  \ 'ctrl-t': 'tab split',
  \ 'ctrl-b': 'split',
  \ 'ctrl-v': 'vsplit',
  \ 'ctrl-y': {lines -> setreg('*', join(lines, "\n"))}}

" Launch fzf with CTRL+P.

  \ call fzf#vim#grep(
  \ "rg --column --line-number --no-heading --color=always --smart-case " .
  \ <q-args>, 1, fzf#vim#with_preview(), <bang>0)

I also get this error when running the :Buffers command:

Error running cat '/tmp/va2Iesy/6'|'/home/nick/.fzf/bin/fzf' '--color=bg+:#f0f0f0,bg:#fafafa,spinner:#a626a4,hl:#a0a1a7,fg:#494b53,header:#a0a1a7,info:#c18401,pointer:#a626a4,marker:#e45649,fg+:#494b53,prompt:#a626a4,hl+:#a626a4' '+m' '-x' '--tiebreak=index' '--header-lines=1' '--ansi' '-d' '\t' '--with-nth' '3..'

It's also worth pointing out that finding files to open in fzf is still working and I can run :Commits successfully too. I haven't done an exhaustive check on which commands work and fail but it looks like in this case both commands blow up with preview.sh.

What's the output of /home/nick/.fzf/bin/fzf --version?

[nickjj]

Hmm, it's 0.21.1 but I did a git pull in ~/.fzf and running git tag there shows 0.22.0. Looks like I needed to also run ./install.

Thanks. It's working now with the latest master commit on both repos after upgrading fzf.

[ludovicchabant]

Yep, same problem here -- I was stuck on fzf 0.18. Works again after upgrading fzf to 0.22. Thanks!

I landed here because I got an error with a similar report.

It happened after running :PlugUpdate.

I hadn't considered that I might need to check the state of fzf, too. That's silly in hindsight, but one often forgets about these tools after setting them up the first time.

Anyway, brew upgrade fzf brought fzf to the latest version and everything started to work again in Vim.

[junegunn]

@mokagio You can make vim-plug call fzf#install() to automatically download the latest binary after update. This is how it's done.

Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
