Comments on: ruby and gems on os-x leopard

I think I have similar problems with multiple Ruby installations on Mac OS X, leading to strange issues with RubyGems (http://www.railsforum.com/viewtopic.php?id=23018) and Aptana RadRails (http://forums.aptana.com/viewtopic.php?p=21960).

What is best practice here? To:
1. Delete the OS X files (in /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby)
2. Delete the MacPorts files (in /opt/local/bin/ruby). If so, should I overwrite the OS X files when new versions are released?
3. Keep both but change the path somehow?

Any input would be most helpful.

Thanks,

Tom.

I forgot to say that I already had Leopard installed when I did this and it worked fine. No need to downgrade or reinstall Leopard. It can all be done from the command line using your instructions.

I followed your correct instructions (remove all my gems first) and it worked a treat. Thanks. There were some things left over though so I also had to do the following commands before running the ‘hash -r’:

sudo rm /usr/local/bin/gem
sudo rm /usr/local/bin/gem_mirror
sudo rm /usr/local/bin/gem_server
sudo rm /usr/local/bin/gemlock
sudo rm /usr/local/bin/gemri
sudo rm /usr/local/bin/gemwhich
sudo rm /usr/local/bin/update_rubygems
sudo rm /usr/local/bin/rails
sudo rm /usr/local/bin/rake
sudo rm /usr/local/bin/mongrel_rails

So… I need some help. I had installed Ruby before I upgraded to Leopard. When I found out Leopard included ruby and rails, I guessed that I could just use that one. First, following Apple’s instructions, I did all the updates. A test app I made wouldn’t run. I tried deleting the folder with all the original Ruby stuff I had installed before the Leopard update. Still got an error when running, so i commented out the line that specifies which Ruby to use to run the app. App still didn’t run. Basically, what do I do to maybe wipe everything Ruby related and start over? To reiterate: I did the Ruby updates Apple suggested, then deleted the directory I had downloaded and installed all my Ruby stuff to initially, and that’s it. What can I do to get Ruby working?

First “hash -r” will fix a file not found error in the current shell. “hash” by itself will show you where the current shell thinks the file is located.

Second check out my post for a way back to Leopard that fixes the Railes Requires RubyGems error and restores the ability to fearlessly do “gem update –system” and even “gem update”. Which updates all gems and was the start of my troubles.

Thanks for pointing me in the right direction! I had used Migration Assistant to move from a PPC box to an Intel box, and thus my woes began…

I took a slightly different approach, removing only some of the files from /usr/local/bin. Hopefully this doesn’t come around to bite me. File lists (including pesky ImageMagick and RMagick files) can be found on my “sister post” at http://www.idolhands.com/blog/2008/02/03/ruby-on-leopard/

Thanks man. Sounds like a big pain in the ass. I think I’ll leave mine alone.
