I can’t blame them I guess, since there’s so many web technologies that run happy on older versions of ruby. The official ruby site did mention it’s an old and stable version from apt-get, but they didn’t mention we should grab a newer one. I didn’t want to use a Ruby version Manager like rvm or vbenv, turns out that’s still the simplest way, and the few extra commands give a great return on investment in the future. Gems from GitHub Pages need at least v2.0 up. As someone that just wanted to get started with setting things up and exploring Ruby and Jeykll as a static-site generator, I couldn’t care less about versions (If it works, don’t fix it, right?). For one, installing the GitHub Pages gem did not mention if I need sudo or not, installing the Ruby using apt-get in Ubuntu/Debian yielded an old version, (1.9.3) as or writing. However, I ran into is simple yet frustrating installation issues. There have been a lot of guides and tutorials on setting up GitHub Pages, Ruby, Jekyll and the related gems needed for GitHub Pages.
