zsh compinit: insecure files, run compaudit for list. Ignore insecure directories and continue [y] or abort compinit [n]? 输入compaudit后输出如下： /usr/local/share/zsh/site-functions/_brew /usr/local/share/zsh/site-functions/_brew_cask /usr/local/share/zsh/site-functions/_brew_services /usr/local/share/zsh/site-functions/_carthage
多次尝试该权限无果，解决办法如下，需要更新4个文件的所有者：
sudo chown root /usr/local/share/zsh/site-functions/_brew
Cheers~
