Describe the bug

what I inserted to .zshrc:

# Download Znap, if it's not there yet.
[[ -r ~/znap_repos/znap/znap.zsh ]] ||
    git clone --depth 1 -- \
        https://github.com/marlonrichert/zsh-snap.git ~/znap_repos/znap
source ~/znap_repos/znap/znap.zsh  # Start Znap

then I execute source .zshrc, I got:

❯ source .zshrc
