brew 安装报错 Running Homebrew as root is extremely dangerous and no longer supported.

最近新换了台mac pro本，用 brew 安装东西时报错，查网页资料说好像是新系统的问题，之前的本没有遇到这问题

sudo brew install pandoc
报错：

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.

网上查询后说是需要 /usr/local 的管理员身份
sudo chown -R $(whoami) /usr/local

但执行该命令又报错
chown: /usr/local: Operation not permitted

还有说执行
sudo chown -R $(whoami) $(brew --prefix)/*
但试过没用

最终

在 Homebrew 官网看到，苹果最新系统用下面命令试试

mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
