zsh 缺少 /usr/local/share/zsh/site-functions/_brew_cask

compinit:503: no such file or directory: /usr/local/share/zsh/site-functions/_brew_cask_学无止境-优快云博客

解决方法：

找个_brew_cask添加到Homebrew/completions/zsh文件夹中

将下面内容添加到_brew_cask文件中，文件没有后缀

#compdef brew-cask
#autoload

# Zsh Autocompletion script for Homebrew Cask
#   https://github.com/homebrew/brew

# Authors:
#   Patrick Stadler (https://github.com/pstadler)
#   Josh McKinney (https://github.com/joshka)

# only display the main commands (but enable completing aliases like 'ls')
zstyle -T ':completion:*:*:*:brew-cask:*' tag-order && \
	zstyle ':completion:*:*:*:brew-cask:*' tag-order 'commands'
