I have followed the instructions to install ruby 1.8.7. Everything seems
to have installed as best that I can determine.
However when I run the command
ruby -v
I get
ruby 1.8.6 (2009-06-08 patchlevel 369) [universal-darwin9.0]
Why is that?
Also do I have to tell my Rails application to use 1.8.7 and if so how
do I do this?
Thank you in advance
Mitchell

Which instructions? What did you do? On what platform? The question
as-is is missing important information.

Then I can guess you're on a Mac, at least.

"which ruby" will tell you where it found it. Presumably your other
installation is either not in $PATH or is later in $PATH; or it was
installed under a different name (e.g. "ruby187" instead of "ruby").

You will probably need to reinstall all your gems, including rails,
using 1.8.7 so they will go in 1.8.7's gems directory. If you build ruby
from source, then you will likely need to build rubygems itself from
source first.

running "whereis ruby" will probably tell you which one it is using, and
if there are multiples on your path or not (it uses the first).
The "whichr" gem will do the same (install it, run "whichr ruby")
Cheers.

Did you do a plain "./configure" or did you add any options to it?
If not, then your new ruby should be in /usr/local/bin. Try this:
/usr/local/bin/ruby -v
If that works, but ruby -v still gives 1.8.6, then show us the output of
echo $PATH

I Did not do any options when I installed. However I have discovered
that my ruby 1.8.6 is installed in /usr/bin/ not /usr/local/bin but my
new ruby 1.8.7 is installed in /usr/local/bin.
Should I reinstall ruby 1.8.7 in usr/bin where ruby 1.8.6 is installed?
echo $PATH
/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
Thanks for your help.

I would just rename /usr/bin/ruby to /usr/bin/ruby_old or something.
But that's just me, and I'm a bit lazy.
