zsh compinit: insecure files, run compaudit for list.

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
