Rails - Jul 2010 - Rails3 rails console throws error

Hi,

I am trying Rails 3 and I am using RVM to manage the ruby versions.

Using RVM I had installed ruby versions 1.8.7, 1.9.1 and 1.9.2

When I do "rails console" I am getting the following error and console
isn''t starting: http://www.pastie.org/1026503

Since I dont require 1.9.1 any more to work with Rails 3, I un-installed
it using the following command:

rvm uninstall ruby-1.9.1

Then also, the console isn''t working. Please help.

This error means you did not have the required dependencies to install 
readline during installation of ruby. If you can find the location of 
the ruby source files in your system, you can go to the ext/readline 
folder. In there there should be an extconf.rb which you can run with

ruby extconf.rb

This will fail but it will tell you what dependencies is missing. You 
would have to install those first. I don''t know what OS you are using 
but when I had this error in CentOS I had to install a few packages from 
yum before I could run extconf.rb successfully. After this it will 
generate a make file which is just like installing any other package 
from source.

Kenneth,

Thanks for the reply. I am using Ubuntu 10.04 and RVM to manage 
different ruby installations.

I had to do:

rvm package install readline
rvm remove 1.9.2
rvm install 1.9.2 -C --with-readline-dir=/home/syed/.rvm/usr/

following the instructions here: 
http://rvm.beginrescueend.com/packages/readline/ and with help from 
Sutto at #rvm irc.freenode.net

I didn''t try your solution, though I am sure it works.

Thanks once again.
