Correct me if I am wrong but your fundamental problem is that somehow
the rails environment is messed up. Your proposed solution is to
delete it all and start again. No-one seems to know how to do this,
though you do know how to remove individual gems (you did it for rails
2.3.8) so you could do this for each of the gems you do not want. You
still have the problem that somehow
rails -v
does not work so somehow you have lost the rails startup script.
Uh, “somehow”?? It was deleted when the gem was uninstalled, as a
previous post showed.
Select gem to uninstall:
- rails-2.3.8
- rails-2.3.8
- All versions
3
Remove executables:
rails
in addition to the gem? [Yn]
Removing rails
Successfully uninstalled rails-2.3.8
The easiest thing to do would be sudo gem uninstall rails to get rid
of all the rails versions and then install the one you want.
I would certainly do that before trying to manually remove the gems,
though that’s trivial (use gem env to find where they are and delete).

I thought uninstalling rails 2.3.8 would uninstall that version then a
different version would be “current”. I paused at that question. I have
to admit.
BTW…

Looks like several versions of rails are still hanging around!
But…
sudo gem uninstall rails

And…
gem list -d rails

Web-application framework with template engine, control-flow layer,
and ORM.
FYI
So it looks like heading over to
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8
and deleting gems/* may do it. In this directory there is an alias to
/Library/Ruby/Site and one to /Library/Ruby/Gems, which has some
interesting content.
So, Mr Schroeder, given this:
gem env

What do I drag to the trash? Looks like the stuff in the three GEM
