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

Uninstall ruby and then install agains:

brew uninstall -f ruby
brew install ruby

Add this two line to you ~/.bash_profile

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

Reopen the console and that's it and run

ruby -v
