How to update version

Hi, I'm running Mac OS X and I'm trying to update my version of Ruby. I
downloaded 1.8.6 and installed, but typing "ruby -v" at the terminal
still shows 1.8.2. How do I fix this?

Hi Iskaldur,

assuming that the installation process went otherwise smoothly,
I guess that your system doesn't know the path to look for the
new ruby installation.
So you might consider to create a symbolic link of a file
ruby186 to the newer ruby as described here

Macworld - News, Tips & Reviews from the Apple Experts,

if you want to keep several versions of ruby.
Otherwise, you could just remove the old ruby from the system and
then install the newer one.

Best regards,

Axel

Make sure you have the directory in which you installed Ruby in your PATH preceding /usr/bin. If you took the defaults during installation, that would be /usr/local/bin, so in your .profile file your PATH statement would look something like this:

export PATH=/usr/local/bin:$PATH

You can find out which directory OS X is getting Ruby from by typing

which ruby

in Terminal.app.

If you don't understand PATH and .profile, you can read about them by starting Terminal.app and typing "man bash". (I'm assuming you're using bash as your shell. New releases of OS X use bash by default.)
