How to get Readline support in IRB using RVM on Ubuntu 11.10

Question

I have tried everything I can think of to get this to work, to no avail so here I am requesting suggestions on how to debug.

Firstly, runnning Ubuntu 11.10

Answer 1

My setup is ubuntu 11.10, RVM 1.10.2, ruby 1.9.3.

This readline problem was giving errors when running irb, and prevented running of the rails console due to the error:

'require': cannot load such file -- readline (LoadError)

The solution that worked for me was the one described by Bryan Larsen, i.e.

DO NOT pkg install readline, with or without --skip-autoreconf

Do the apt-get install that rvm requirements tells you to do, then

rvm --skip-autoreconf pkg uninstall readline

rvm remove 1.9.3

rvm install 1.9.3

Thx for the tip Bryan.
