After using "rbenv install 2.3.0", I successfully installed 2.3.0
Then I used "rbenv global 2.3.0"
now when I use "ruby -v" the terminal returns
ruby 2.0.0p645 (2015-04-13 revision 50299) [universal.x86_64-darwin15]
So the ruby version I get from terminal is not the same i installed with rbenv. Is there anything I'm missing? How do I get ruby -v to return the version that I installed with rbenv?

19,236 PointsIn case anyone revisits this question, I resolved this by typing this exact line into the command line:
export PATH="$HOME/.rbenv/shims:$PATH"
then ruby -v will then return 2.3.0 (or whatever version you installed). But I have to retype it every time I start a new session.

19,236 PointsThanks for answering Nate. Obviously I am very new to this, so what would it mean to update the PATH? When I copy and paste the step 2 line, it doesn't seem to really do anything (the terminal does not return anything and ruby -v still returns 2.0.0).
Can you give me an example of how to permanently change the PATH to the .rbenv installed version of ruby?
