I got the following error when I try to run the console. It used to be able to run without problems.

script/console

Have you tried    http://www.oobaloo.co.uk/articles/2006/03/22/ruby-and-readline    http://ruphus.com/code/rails/railsonubuntu-howto.html

Thanks for the links.

I found that my ruby was not built with readline support because I downloaded and installed the latest version 1.8.6, not the Ubuntu package. What I did to fix it was to rebuild ruby with readline support:

./configure --with-readline-dir=/usr/local make make install

Now script/console works as expected. However, before I included the readline support, irb works but not script/console. Why?

Ray,
