hi,

i’m a noob in ror, today i bought a book to learn ror.

i do everthing that stand’s in this book, and the shit does’t work!

i use Aptana IDE with RadRails

the problem is:

Loading development environment.  
/usr/lib/ruby/1.8/irb/completion.rb:10:in `require': No such file to load -- readline (LoadError) from /usr/lib/ruby/1.8/irb/completion.rb:10 from /usr/lib/ruby/1.8/irb/init.rb:218:in`require’  
from /usr/lib/ruby/1.8/irb/init.rb:218:in `load_modules' from /usr/lib/ruby/1.8/irb/init.rb:216:in`each’  
from /usr/lib/ruby/1.8/irb/init.rb:216:in `load_modules' from /usr/lib/ruby/1.8/irb/init.rb:21:in`setup’  
from /usr/lib/ruby/1.8/irb.rb:54:in `start’  
from /usr/bin/irb:13

when i use the shell myapp/script/server it starts without any problems.

any body know how i can fix it?
