How to read rdoc in Emacs

Question

I'm now using to read RDoc gem server command. But I want to read document in Emacs.

I found a emacs lisp for it called [yari][1], but it doesn't worked in my environment. I called a function yari and typed in the minibuffer yari: Array, but result was yari: Array[not matched].

I don't insist to use yari, it is ok if I can read rdoc in Emacs. Is there any way that is commonly used?

The most common reason for yari not working is that you probably installed your ruby and its gems without their docs. If you're using RVM you should do this:

rvm docs generate

I think I've already installed RDoc correctly. I can see rdoc by using `gem server` and to be sure I've reinstalled all rdocs by `gem rdoc --all --ri`. – ironsand Dec 08 '13 at 21:34

This worked for me:

gem install rdoc-data
rdoc-data --install
