推荐使用 rvm 安装 ruby 环境会好一点， 不依赖sudo 写 bin目录

可以参考 https://ruby-china.org/wiki/rvm-guide 安装 2.4 以上的ruby 版本均可

如果必须用原生， 可以参考下面的指令
xcode-select --install
sudo xcodebuild -license
brew install ruby
brew install coreutils

gem install fir-cli

其实这个报错是因为 unf_ext 没装上， 原因是缺失一些组件

brew install ruby 现在会安装 ruby3, 会导致执行失败
