Doh! Two versions of Ruby installed!

Hey all

I installed FXRuby today using macports and i believe it’s installed
another copy of Ruby in /opt/local/bin/ruby

ls -l which ruby # => -rwxr-xr-x 2 root admin 13412 Aug 1
16:50 /opt/local/bin/ruby
cat 'which gem` | head -n 1 # => #!/usr/local/bin/ruby

This means that when I try to start up irb or write ruby in TextMate,
none of my gems can be found.

LoadError: no such file to load – rubygems

can anybody advise how can I sort this screw-up please !?

remove the new version
re-install your gems using the new version
fix your PATH so which ruby returns your original version

I’d go with door #3, personally

Huh? Home and End work fine on Mac OS X. So do Ctrl-A and Ctrl-E.

A generic follow up:

upgrade to Ubuntu (your Home and End keys will start working, too!)
use ‘whence ruby’ for more info
symlink the ruby you want to a spot higher in the PATH

Thanks for the suggestions guys

I opted for completely removing my old build and all of the gems in
favor of the new one (as it was in opt/local as opposed to usr/local)

It’s been a messy learning experience but all is working fine now,.

:S

Woa - lets not bring OSX into this.

She’s beautiful!

the issue for me was installing FXRuby through macports which re-
installed ruby in another location on my hard-drive.

FXRuby and me are to blame!

:S

So, other than installing multiple Rubies to several different uncommon
folders, and making you use two keystrokes for the more common operation
(moving to the beginning and the end of the lines), Macs are indeed

Gift to Usability!

As Gavin said, that was user error. Leopard comes with a perfectly fine
Ruby installation already.

Get your facts straight, Phlip. In most Mac apps, Home and End do go
to the beginning and end of the line. Generally Cmd-Home goes to the
beginning of the file.

(And on my laptop, there’s no keystroke benefit anyway; Home and End
need the Fn key, and because of the key layout, I can do Ctrl-A and
Ctrl-E with one hand.)

Macs are indeed
God’s
Gift to Usability!

Absolutely. Linux is great for servers, but I’ll take Mac OS for a
desktop OS any day.

And I have to say, Phlip, I really think that you are God’s Gift to
Testing, but I’m not sure why you feel it necessary to post
mean-spirited, inaccurate information like this in other subject
areas…

Phil, do you have a blog?
