It says "can't find header files for ruby at:

/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/include/ruby.h

Have you looked to see if that file exists? I'm guessing that it is expecting ruby header files at that location and they aren't there. I have version 2.6 as my system ruby and the path does not have /include inside the ruby folder. I don't think they include the source files for the system ruby. But if you look in the SDK folders you should find it. I found it here:

/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/ruby-2.3.0

Usually when a gem fails to install it will tell you a bunch of flags you might need to use to specify locations of files. There is an known issue with Ruby versions of less than 2.4 and cocoapods: https://github.com/CocoaPods/CocoaPods/issues/9641

I would either install ruby > 2.6 using RVM and see if it will find the source code files, or if you have the headers installed with the command line tools like I do you can try a flag like:

sudo gem install cocoapods -- --with-ruby-include '/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/'

Note the two dashes before the second set of dashes for the flags, that is usually required for passing these flags.
