Sorry, I forgot to tell the group to e-mail me updates on the post. I'm sorry, Colin is right, what I wrote was just an example. > I expected after deinstalling rails 2.3.8 gem list local would find the > other rails versions. But did this blow away all rails? The gem command is being cautious. It doesn't want to delete anything but the absolutely necessary. I personally would not want to remove a gem and find out that the command blew away 10 other gems just because they are either required by the one I just deleted or compatible with it. What if I wanted to keep them because they serve me for other purposes? Removing gems is a little boring but it shouldn't take you more than 10 or 15 minutes to remove all the ones you need to remove once you get the hang of it. > I admit I am in learning mode.

I cannot figure out > rvm, After reading an entry on the internet I tried just that a week or so ago as the entry specified that it _might_ be possible. However, after I blew away all folders in the gem directory and asked for the gem list all the gems were still there and I had to run the commands manually anyway to make sure everything was gone as it should. I didn't want to have problems during re-installation. You're going to need to uninstall the gems manually and probably selectively I'm afraid, but if you find a way to do it all at once, please let me (us) know. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
