_ftb__main_complete command not found

[fjchen7]

Describe the bug

A clear and concise description of what the bug is.

I can make sure:

• I am using the latest version of fzf-tab
• this is the minimal zshrc which can reproduce this bug
• fzf-tab is loaded after compinit
• fzf-tab is loaded after plugins which will wrap Tab, like junegunn/fzf/completion.zsh
• fzf-tab is loaded before zsh-autosuggestions, zsh-syntax-highlighting and fast-syntax-highlighting.

To Reproduce

Steps to reproduce the behavior:

1. Type 'cd'
2. Press Tab
3. See error

Expected behavior

Show completion memu.

Screenshots

However sometimes it show permission denied

Environment:

• OS: macOS 15.5
• zsh version: zsh 5.9 (arm-apple-darwin24.2.0) (/opt/homebrew/bin/zsh)
• zimfw: 1.18.0

Minimal zshrc

.zshrc

# -----------
#  Zim setup
# -----------
# Set directory where Zim will be installed
ZIM_HOME=${ZDOTDIR:-${HOME}}/.zim
# Download zimfw plugin manager if missing.
if [[ ! -e ${ZIM_HOME}/zimfw.zsh ]]; then
  curl -fsSL --create-dirs -o ${ZIM_HOME}/zimfw.zsh \
      https://github.com/zimfw/zimfw/releases/latest/download/zimfw.zsh
fi
# Install missing modules and update ${ZIM_HOME}/init.zsh if missing or outdated.
if [[ ! ${ZIM_HOME}/init.zsh -nt ${ZIM_CONFIG_FILE:-${ZDOTDIR:-${HOME}}/.zimrc} ]]; then
  source ${ZIM_HOME}/zimfw.zsh init
fi
# Initialize modules.
source ${ZIM_HOME}/init.zsh

.zimrc

# Use degit instead of git submodules for faster cloning
zstyle ':zim:zmodule' use 'degit'
zstyle ':zim:completion' dumpfile "${XDG_CACHE_HOME:-$HOME/.cache}/zsh/.zcompdump"

zmodule environment
zmodule input

zmodule zsh-users/zsh-completions --fpath src
zmodule completion
zmodule Aloxaf/fzf-tab

zmodule zsh-users/zsh-autosuggestions
zmodule zsh-users/zsh-syntax-highlighting

Log

If applicable, use C-x . to trigger completion and provide the log.

If there are only three lines in your log, please make sure your fzf-tab is loaded with the correct order (see the checklist above).

[Aloxaf]

I cannot reproduce the bug with your zshrc. Please provide the log.

I am also facing this issue. I am on macOS 15.5 too. I am using zinit, which are different with OP's.

My result on pressing TAB after typing ls showing this:

_ftb__main_complete:143: command not found: _ignored

[Aloxaf]

@minty99 Can you put autoload -Uz compinit; compinit before fzf-tab and try again?

[minty99]

@Aloxaf it works! thank you. But I don't know why it works - could you explain? Is the line necessary?

[Aloxaf]

@minty99 This is used to initialize the zsh completion system. Frameworks like zimfw usually handle this for you, but if you're using a plugin manager like zinit, you'll need to call it yourself.
