Help! Window user needs help installing ruby 1.9 on mac

I just purchased a new macbook pro and would like to install ruby 1.9,
but I’m having trouble installing, can someone please provide the
easiest steps to install ruby 1.9 please?

Thanks

Install macports. Then:
sudo port install ruby19

Should do it.

Thanks Ben, that helped a great deal, 1.9 is installed successfully on
my machine.

Kindest Regards

Great. You’ll find macports pretty handy for installing many things.

Cool. One thing I’m noticing is when I type /usr/bin/ruby -v it is
giving me version 1.8, when I’m compiling my code how do I know which
version of ruby I’m using? 1.9 is installed in my /opt/local/lib
directory.
Should I uninstall 1.8?

Thanks

at the prompt, type which ruby and that will give you the
path to the executable

also, you might want to check your PATH env variable to make sure it’s
finding the right one first, although I think OSX has a mechanism for
switching that’s kind of a half baked version of the Linux
alternatives mechanism for switching between various versions of
“stuff”. Although, in fairness this seems to work quite well for java
on the mac. Anyway, check your path with either echo $PATH of env
commands and see what it says. You may have to force it by modifying
the path in .bash_profile in your home directory (assuming bash) or
some other file that’s modifying your path variable. Hope that helps.

Take a look at this article:

Although it is a little hackish I’m not sure of any easier method.

Sorry but I cannot find the file to modify my path env variable.

Thanks

I always install alternative versions of any software into different
directories, e.g.
/usr/local/ruby-1.8.6
/usr/local/ruby-1.8.7
/usr/local/ruby-1.9.1

set the default path in your .bashrc.local or equiv, and then use a
file like, say “r187”

export RUBY_HOME=/usr/local/ruby-1.8.7
export PATH=$RUBY_HOME/bin:$PATH

for each version. Then in any window you can type
prompt> . r187

and set the version for that particular shell.
