Cannot get OS X to use my rbenv installed ruby version

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?

In 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.

I added that PATH to my .zshrc file and it now stays on current version of Ruby. If you're not using zsh you could try pasting it into your .bash_profile.

You either need to reload your shell (just open a new one), or update your PATH. Walk through the rbenv setup instructions again.

Thanks 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?

I think the issue has to do with the version of OSX. I am using 10.10.5 and I think the ~/.bash_profile has been changed for this version onwards. Can anyone confirm this?

The command is executing but I am still getting the original version from OSX...
