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

Have you tried

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?
