Ruby on Rails console error

[barrysfarm]

I'm very new to the ruby on rails stuff, and i'm having a problem accessing the console. I've tried googling, but couldn't find anything that explained how to fix it. I've got ruby 1.8.2 installed (the universal binary version). I'm on a macbook. I'm a kind of stuck, so if anyone could offer their advice, i'd appreciate it.

How did you install ruby?

Edit: I think it may have been configured without readline support. I followed this guide when I setup my environment - http://hivelogic.com/articles/2005/12/01/ruby_rails_lighttpd_mysql_tiger

too bad I haven't done much since.

I downloaded ruby gems from rubygems.rubyforge.org, then went:

tar xzf rubygems-0. {whatever the version # was}
cd rubygems{folder}
sudo ruby setup.rb

sudo gem install rails --include-dependencies

As far as I can tell, the rest of ruby & rails works. I'm able to set up models & scaffolding, and have it interact with my mysql database.

Thanks, I'll try reinstalling it all.

So you never setup Ruby itself? If you are using the default Ruby install that comes with Tiger, it didn't include readline. Good luck with the reinstall

I guess not. I did it directly from a book (Beginning Ruby on Rails, Steven Holzner), which doesn't seem to be worth what i paid for.

I'm somewhat new to working with the terminal. Should I uninstall my current installation or just install over the old installation?

Well the default ruby install is /usr and the new install will be in /usr/local - so no uninstall is necessary. Take note of the step where you modify the PATH env variable - thats what will allow you to use the newer version instead of the default.

I got to imagine that someone has simplified this process, but haven't bother looking since this was linked to right out of ADC at http://developer.apple.com/tools/rubyonrails.html

Reinstalling with the tutorial provided seems to have fixed it.

Thanks for all your help!
