1. brew install nginx
   提示没有权限

Error: The following directories are not writable by your user:
/usr/local/include
/usr/local/lib

2.sudo brew install nginx
提示不支持

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.

3.加权限 sudo chown -R $(whoami) /usr/local
提示当前操作系统不支持

chown: /usr/local: Operation not permitted

4. stackoverflow 查到 sudo chown -R (brew --prefix)/*

sudo chown -R mac brew
brew install nginx

成功!

        #access_log  logs/host.access.log  main;

        location / {
            proxy_pass http://localhost:8080; //②这里指向本地
