Nothing Known About … when using ri Array — Ruby

Question

I have Ubuntu 11.10 and am using rvm with ruby 1.9.2. I followed this exactly to install Ruby: http://blog.sudobits.com/2011/10/27/how-to-install-ruby-on-rails-in-ubuntu-11-10/

I generate the docs with

rvm docs generate

This seems to work for a one time terminal session, but as soon as I exit out and start again, I have to generate the docs again, otherwise i get the Nothing is Known error This takes a long time, so I rather not have to generate the docs every time I start a terminal session.

Is there anything I can do to permanently have the docs available?

There are definitely similar questions to this -- but I don't have a problem with generating the docs, or using them, just keeping them installed.

Answer 1

This is what I did to install ri docs on my Ubuntu box (I'm not using RVM):

gem install rdoc rdoc-data
rdoc-data --install

Answer 2

In ubuntu: sudo apt-get install ri1.9.1
