ERROR: Failed to build gem native extension. basically means that while installing a gem, ruby wasn't able to compile some C code nested inside that gem. You could see the details of process if you run gem install sqlite3 --verbose That could come either from environment improper set up or from missing or incorrect configuration flag you have to provide in order for the C compiler to work. I'm not a windows guy, when the issue pops up in Mac OS, it usually deals with xcode-select. Have you ever tried this kit?

On the other hand I would recommend you to build your own virtual machine with Virtual Box and Vagrant or choose VM that treehouse guys have already built for us. That gives you clean configuration of your project environment and spares you of these annoying compatibility issues.
