:Rg test failed

I saw similar issues like this one, but they provided empty query, I'm not. I can run this command in terminal success. rg version:

This is my .vimrc about fzf:

  function! RipgrepFzf(query, fullscreen)
    let command_fmt = 'rg --column --line-number --no-heading --color=always --smart-case %s '
    let initial_command = printf(command_fmt, shellescape(a:query))
    let reload_command = printf(command_fmt, '{q}')
    let options = {'options': ['--phony', '--query', a:query, '--bind', 'change:reload:'.reload_command]}
    call fzf#vim#grep(initial_command, 1, options, a:fullscreen)
  endfunction

  command! -nargs=1 -bang Rg call RipgrepFzf(<q-args>, <bang>0)

:Rg returns command not found for me, too

Run the command in the error message in your shell and check the exit code. If it's non-zero, fzf displays the message.

I check the exit code by run echo $? in my shell, but the result is zero.

maybe u should run rg in your shell first.

This rg man page says:

If ripgrep finds a match, then the exit status of the program is 0. If no match could be found, then the exit status is 1. If an error occurred, then the exit status is always 2 unless ripgrep was run with the --quiet flag and a match was found.

The fzf code appears to report the "Command failed" error if the command didn't exit with status 0 and produced no output, which is the case when ripgrep matching no lines.

So, I think that for no search results this is the expected behaviour.
