使用 brew install ** 指令

报错
The following directories are not writable by your user:
/usr/local/share/man/man8

You should change the ownership of these directories to your user.
sudo chown -R $(whoami) /usr/local/share/man/man8

And make sure that your user has write permission.
chmod u+w /usr/local/share/man/man8

解决方案
使用如下指令获取usr/local文件夹的写入权限

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

重新调用 brew install ** ，即可正常完成安装
