I'm trying to learn Ruby, and one of the most common ways I found of installing it is through RVM. After running rvm install 2.1.2 to get the latest version it seems to complete fine, but when doing ruby -v this output is shown:
chris@ubuntu:~$ ruby -v
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]
which is the wrong version. Doing rvm list shows only 2.1.2:
chris@ubuntu:~$ rvm list
rvm rubies
=* ruby-2.1.2 [ x86_64 ]
Doing a rvm reinstall 2.1.2 also completes fine, however I still end up with the wrong Ruby version installed. Here's the output for that:
chris@ubuntu:~$ rvm reinstall ruby-2.1.2
ruby-2.1.2 - #removing rubies/ruby-2.1.2..
Searching for binary rubies, this might take some time.
Found remote file https://rvm.io/binaries/ubuntu/14.04/x86_64/ruby-2.1.2.tar.bz2
Checking requirements for ubuntu.
Requirements installation successful.
