There is a bunch of ways to install Ruby, what is the proper way for Tisquel?

For whatever reasons the version of Ruby that one can get in the Trisquel repos is old. Too old to be useful. I try to install Jekyll and get this -
grey@x60:~$ sudo gem install jekyll
ERROR: Error installing jekyll:
jekyll requires Ruby version >= 2.0.0.
There are a few different way to go about installing Ruby, like RVM. But with RVM I can basically only use the Ruby that RVM provides, from the terminal. Other programs don't 'see' that it's there. I've found a few other answers as well. So what should I use? I thought the link at the bottom MAY work but it's pretty old. You thoughts, please? Thanks.

Wow, great typo.
Ruby 2.0 is in the repos of Trisquel 7.0.
It does say that, but installing the ruby2.0 package actually gives you ruby1.9.3, I don't know why, but it does.
sudo apt-get install ruby-full
Try that?
The ruby-full package provides Ruby 1.9.3, which is an old stable release, on Debian and Ubuntu. So just update it?
Reference: https://www.ruby-lang.org/en/documentation/installation/
Install ruby2.0 and ruby2.0-dev.
Installing both of those on my system actually gave me Ruby1.9.3.
I'm not familiar with Ruby, but I suspect you've actually got two ruby binaries, because Ruby 1 is still there, and that Ruby 1 is the one called "ruby". Kind of similar to how there's Python 2 and Python 3, but only Python 2 gets to be aliased to "python". :) Did you try something like "ruby2"?
I am a translator!
That's right Onpon. I have a ruby and a ruby2.1 here.

This is likely the case.
Speaking as a Ruby developer, you're better off just not using Ruby
version provided from apt. Use a utility like rbenv (my personal
favorite), chruby, or rvm (as a last resort) with ruby-install or
ruby-build.
Ruby is a mess.

So why rbenv?

Strictly because it's the one I know the most because it's imposed at
work. I tend to personally prefer chruby because it is the simplest in
design.
A while back, there was a lot of fuss about Ruby in apt with the Debian
folk. I don't recall all the details but there was some squabbling
over 1.8 and moving to 1.9/2.0. From that point forward, I've never
trusted system ruby.
Additionally, using something like rbenv or chruby allows you to have
the most recent ruby installed locally in userland. If you combine it
with something like chgems, you can isolate gemsets should you run down
the rabbit hole of too many gems being installed on the system (often a
real problem when versions aren't explicitly declared).
