rbenv can't change global ruby version

Question

My Mac OS X has a default ruby.

$ ruby -v
ruby 2.0.0p451 (2014-02-24 revision 45167) [universal.x86_64-darwin13]

I installed rbenv and ruby ver

Answer 1

I realize that I occasionally set local ruby version in home folder, from which I use terminal by default :) So that's what worked for me:

rm /home/MYUSERNAME/.ruby-version
