Cannot get OS X to use my rbenv installed ruby version

After using homebrew to 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]

I saw in https://teamtreehouse.com/community/cannot-get-os-x-to-use-my-rbenv-installed-ruby-version Matthew pasted in export PATH="$HOME/.rbenv/shims:$PATH" it worked for him but I just get in my command line:

And when I exit out of whatever that and check ruby -v it says:

ruby 2.0.0p645 (2015-04-13 revision 50299) [universal.x86_64-darwin15]

but when I do rbenv global command it displays '2.3.0' as the current version...

HELP PLEASE!

Hi,

You can place the command 

export PATH="$HOME/.rbenv/shims:$PATH"

under /Users/your_user/ directory either one of the (or both) files named .bashrc and/or .bash_profile and run following command(s):

source /Users/your_user/.bashrc

or 

source /Users/your_user/.bash_profile

Kenan Memis thank you! I don't know what you did but the .bash_profile worked - could you please explain what was going on in those commands? For me at this stage it's just magic ha.

Hi,

:) Okey when you just call "export ... " command on command line, you (generally) execute the command for that session of terminal window. When you close the terminal or open a new one, you see that you do not have the result of the command that you previously run.

so, bashrc and/or bash_profile files are good choices for such commands in order to run in every single terminal window, or session. These files are scanned and the code processed for whole system when you start your operating system.

Since you placed a new code to these files after your OS started, by running source command you just reload those files and the newly added code snippet also works for whole system :)
