我是新人，第一次接触cita。在官方文档里找到 homebrew-cita的GitHub页面，按照上面的步骤安装cita，结果碰到如下的问题，有大佬解答下吗：
新人关于cita在mac上安装的问题
GitHub 上的文档有点问题，谢谢反馈！
如果用 brew install cita 安装, 请直接执行：
cita create --super_admin "0x141d051b1b1922bf686f5df8aad45cefbcb0b696" --nodes "127.0.0.1:4000,127.0.0.1:4001,127.0.0.1:4002,127.0.0.1:4003"
GitHub 上的文档已经修正：
谢谢！
解决了嘛，bro @Alvin_lu

理想情况下应该是这个样子:
𝝺 brew tap cryptape/cita
𝝺 brew install cita

By default, binaries installed by cita will be placed into:
/usr/local/opt/cita/libexec
Usage: cita_commander <command> <node> [options]
where <command> is one of the following:
{ help | create | port | setup | start | stop | restart
ping | top | backup | clean | logs | logrotate }
Run `cita help` for more detailed information.
happy hacking!

brew install coreutils
参考：
同时在上次的分享中我也专门提到了这个问题，有兴趣可以回看这次分享：
