You can simply remove the doc directory in the RubyGems installation directory.

rm -r `gem env gemdir`/doc

On Mac OS X by default, it's /Library/Ruby/Gems/1.8/doc.

Keep in mind that there might be several installation directories for RubyGems.

  • RubyGems will try to install to your user directory (something like ~/.gem/ruby/1.8/) if it can't access the normal installation directory (e.g. you installed a gem without sudo).
  • RVM also installs RubyGems for each Ruby it installs which will contain a doc directory containing rdoc and ri files (e.g. ~/.rvm/gems/ruby-1.9.2-preview1/doc).

This will merely remove existing files, but new ones will come with new installations anyway, unless you use the --no-document flag for gem install or make it a default.

    `--no-ri --no-rdoc` has been deprecated in favor of `--no-document`, but this answer works the best. – bayendor Jul 06 '14 at 13:10

It worked for me when I tried this:

gem rdoc <gem name> --no-ri --overwrite

Then you can remove only ri of the gem, and leave the gem itself. I don't see we need any other way around for this.

  • Do you think I didn't understand the question? The question was "How can I remove the ri and rdoc of installed gems?" :) – kangkyu Jul 12 '16 at 18:53
  • You asked the OP to *try* something, which sounds like a guess, and hence a comment. If you are sure of what you are writing in your answer, I don't see why you'll use such words. – CinCout Jul 13 '16 at 05:19

I just had this problem to, after thinking it would be a good idea to have some local rdoc for the train etc, I completely filled up my disc!

So, I bit the bullet, and did it (the hard way).

First, this is how I got in this stupid predicament :-

$ gem install rdoc-data
$ rdoc-data --install
$ gem rdoc --all --overwrite

To undo this, I thought I'd uninstall the gems, and then install them as needed (but without rdoc!)

  1. Get list :-

    $ gem list

*** LOCAL GEMS ***

aasm (2.1.1)
actionmailer (3.2.3, 3.2.2, 3.1.4, 3.1.3, 3.1.1, 3.1.0, 2.3.8, 2.3.5)
actionpack (3.2.3, 3.2.2, 3.1.4, 3.1.3, 3.1.1, 3.1.0, 2.3.8, 2.3.5)
active_support (3.0.0)
... +100 ...

  2. Copy and search/replace \(.*\) with '\'

  3. Bulk uninstall :-

    $ gem uninstall actionmailer \
actionpack \
active_support \
... 100 more ...
ZenTest \
-a -x -I

  4. Watch as the disc gains GB's of free space! (~11GB!)

Twas a stupid idea in the first place, and my solution may be just as much so, but it worked.
