How to know the lastest version of ruby in Terminal?

Question

I intend to install ruby by rvm to my Macbook Pro, with the command tutorial:

$ rvm requirements
$ rvm install 2.3.0
$ rvm use 2.3.0 --default

But you know the 2.3.0 maybe not the newest version, because the tutorial is long time ago.

So, how can I get the lastest version of ruby in command?

Do you actually want to install the latest version of RVM or do you want to use RVM to install the latest version of Ruby? — Holger Just, Jan 15 '17 at 23:49
@Holger Just, yeah, i want `rvm install 2.3.0` the meaning, it is ruby version, alright? — aircraft, Jan 15 '17 at 23:51

rvm get head # update list of known rubies. Necessary if your local list is out of date.
rvm install ruby --latest # install the latest ruby

The latest ruby version (at time of writing) is 2.4.0

I use `rvm get head`, terminal shows:`Downloading https://get.rvm.io No GPG software exists to validate rvm-installer, skipping. Downloading https://github.com/rvm/rvm/archive/master.tar.gz`,and it takes a long time, is it normal ? – aircraft Jan 16 '17 at 01:32
rvm uses GPG to verify the integrity of downloaded rubies. If you have gpg in your path (install varies by system) then that message should go away. I don't know why downloading master.tar.gz would take a while, however... It takes maybe 5 seconds for me. – Glyoko Jan 16 '17 at 01:40

you can run rvm list known to see all options, but 2.3 is pretty new and will be a good choice.
