Mac homebrew install 报错

gnn

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.

解决方法如下：
将下方命令按个执行
sudo chown -R `whoami` /usr/local/Homebrew/
sudo chown -R $(whoami) $(brew --prefix)/*
然后在用brew下载东西，如果还是报错
将下载命令sudo去掉直接：brew install xxxx即可
