Thank you all for your help! I was really having a hard time trying to
figure out how to get the header files. This command solves the problem:
open /Library/Developer/CommandLineTools/Packages/
macOS_SDK_headers_for_macOS_10.14.pkg
Also as far as conflicting version of ruby, I uninstalled the one with
homebrew by typing "brew uninstall ruby" then proceeded to install ruby
with "rvm install 6.2.0"
