I am a newbie and just purchased the Rails 2 by Patrick Lenz book. Thanks for the forum. I have been wanting to learn Ruby and Rails for a long time. I appreciate all the help from everyone on the SitePoint forums. Maybe some day I will be able to contribute help to others.
Best of luck to you 
Another newbie here.
I have installed Ruby on a PC running openSolaris 2009.06.
I installed Ruby 1.8.7p72 and Ruby Gems 1.3.5. , then installed Rails 2.3.5.
MySQL (5.1.41 Community Server) was already installed. I created the Rails application shovell. and I can start the application using ruby script/server. But when I come to use the console I get an error:
ruby script/console
Loading development environment (Rails 2.3.5)
/usr/local/lib/ruby/1.8/irb/completion.rb:10:in require': no such file to load -- readline (LoadError) from /usr/local/lib/ruby/1.8/irb/completion.rb:10 from /usr/local/lib/ruby/1.8/irb/init.rb:252:in require’
from /usr/local/lib/ruby/1.8/irb/init.rb:252:in load_modules' from /usr/local/lib/ruby/1.8/irb/init.rb:250:in each’

from /usr/local/lib/ruby/1.8/irb.rb:54:in `start’
from /usr/local/bin/irb:13
I have looked around on the web and found one suggestion to go back to ruby source code ruby-1.8.7-p72/ext/readline and run the following commands:
ruby extconf.rb
make
make install
But this made no difference.
Any help appreciated.
Did you try installing the updates. You can check here:
http://www.ruby-lang.org/en/news/2009/12/25/ruby-1-8-7-p248-released-/
It looks like this release fixed a bunch of bugs in a previous version.
Try it and then be sure to post if that fixes the problem. Or if it doesn’t. Hopefully it will.
