brew 安装报错 Running Homebrew as root is extremely dangerous and no longer supported.
最近换了公司的MAC（系统10.14.4），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
终端执行 brew install chisel
报错：
RunningHomebrewasrootisextremely dangerous and no longer supported.AsHomebrewdoes not drop privileges on installation you would be giving allbuild 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
最终
在 Homebrew 官网看到，苹果最新系统用下面命令
mkdir homebrew&&curl-L https://github.com/Homebrew/brew/tarball/master|tar xz--strip1-C homebrew
搞定！
