Rails3 rails console crashes throwing error

Question

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:

/home/syed/.rvm/rubies/ruby-1.9.2-preview3/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load -- readline (LoadError)
  from /home/syed/.rvm/rubies/ruby-1.9.2-preview3/lib/ruby/1.9.1/irb/completion.rb:9:in `<top (required)>'
  from /home/syed/.rvm/gems/ruby-1.9.1-p378/gems/railties-3.0.0.beta4/lib/rails/commands/console.rb:3:in `require'
  from /home/syed/.rvm/gems/ruby-1.9.1-p378/gems/railties-3.0.0.beta4/lib/rails/commands/console.rb:3:in `<top (required)>'
  from /home/syed/.rvm/gems/ruby-1.9.1-p378/gems/railties-3.0.0.beta4/lib/rails/commands.rb:20:in `require'
  from /home/syed/.rvm/gems/ruby-1.9.1-p378/gems/railties-3.0.0.beta4/lib/rails/commands.rb:20:in `<top (required)>'
  from script/rails:6:in `require'
  from script/rails:6:in `<main>'

Since I don't 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

Still rails console crashes. Am I doing something wrong?

Answer 1

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
