1. 问题

执行命令:

报错:

2. 解决办法

显然是权限不够引起的问题，添加sudo权限，结果Homebrew不允许root权限下运行。

zzh@zzhdeMBP ~ % sudo brew cleanup
Password:
Error: Running Homebrew as root is extremely dangerous and no longer supported.
As Homebrew does not drop privileges on installation you would be giving all
build scripts full access to your system.

只能求次进行解决，分配文件夹权限给当前用户。

sudo chown -R $(whoami) /usr/local/share

本想分配/usr/local文件夹的权限，结果不行。

运行结果如下。

zzh@zzhdeMBP ~ % sudo chown -R $(whoami) /usr/local
chown: /usr/local: Operation not permitted
zzh@zzhdeMBP ~ % sudo chown -R $(whoami) /usr/local/share
zzh@zzhdeMBP ~ % brew cleanup
