mac install error

[jasonrclark]

Hi @yishuiliunian! So I see two things happening here.

First off, Shoes 4 only works on JRuby and you appear to be installing it on CRuby 2.5.1. If you install a recent JRuby (9.2.0.0 recommended), then you should find that the gem install shoes --pre should work.

Second, the error you're seeing is about one of Shoes' dependencies. If you just do gem install nokogiri I'm betting you'll see the same problem. The text in the middle suggests that you haven't run xcode-select --install to set up some of the necessary Mac development tools for compiling native gems like nokogiri.

Hope this helps out!
