Where is ruby ​​installed?

Question

ruby

Good afternoon everyone. Ruby downloaded, compiled, in general, I thought for a long time and everything seemed to end well during installation, but I can’t figure out where it was installed
apt-get install rvm -y
reload
/usr/share/rvm/bin/rvm install ruby-
2.1. => 1.27.0
ruby ​​-v - ruby ​​program not found
which ruby ​​- empty output
Accordingly, rails is not put further because the gem was not found either. How to be. Previously tried on a 64 bit system - everything worked. And now it's 32 bit, and it doesn't work. But ubuntu version 14.04 in both cases
Option 2 rvm.io/?.
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
\curl -sSLhttps://get.rvm.io | bash -s stable --ruby=2.1.5

How to live on?)))

Answer 1

And if you try to install not via apt-get, but via readme with rvm.io?

Answer 2

It's written:

* To start using RVM you need to run `source /home/deployer/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.

Answer 3

dpkg -L rvm
