# Manual installation (check common locations)
rm -f /usr/local/bin/fnm
rm -f ~/.local/bin/fnm
rm -f ~/bin/fnm

Remove fnm-related configuration from Shell configuration files:

Bash

# Edit ~/.bashrc, remove the following line
eval "$(fnm env --use-on-cd)"

Zsh

# Edit ~/.zshrc, remove the following line
eval "$(fnm env --use-on-cd)"

# Edit ~/.config/fish/config.fish, remove the following line
fnm env --use-on-c | source
