Ruby Docs Update Error

I have MacPorts installed Ruby on Rails which I am have been updating and reworking since yesterday as I want to get back into studying this language.

Specs

ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [i686-darwin10]
rails -v
Rails 3.0.3
gem -v
1.8.5

The Journey

So far it has been quite the journey to get Ruby, Rails and Gems to work on my Mac. On following a tutorial I decided to install/ update Rails API docs and I ran into these errors:

Password:

Installing ri documentation for activesupport-3.2.3...

unrecognized option `--encoding'

For help on options, try 'rdoc --help'

ERROR:  While generating documentation for activesupport-3.2.3
... MESSAGE:   exit
... RDOC args: --ri --op /opt/local/lib/ruby/gems/1.8/doc/activesupport-3.2.3/ri --encoding UTF-8 lib --title activesupport-3.2.3 Documentation --quiet

when I did gem server the server was started up. So I probably installed docs a year ago and totally forgot about it.

What can I do to get rid of all these errors? Or can I safely ignore them and keep on going?

Try gem install rdoc or gem update rdoc if you have rdoc version < 3.0.

RDoc generates Documentation from Ruby Source Files. So, as @Mark Sands says, it's not absolutely necessary to make your code run it can be nice to have and addresses the root of your errors.

I get the same warnings here on Debian linux and I am using rvm with ruby-1.9.3-p194.

I eliminated most of them by changing line 127 of 

~/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/source_index.rb

127 add_spec gemspec if gemspec to 127 Gem::Specification.add_spec gemspec if gemspec

As for the others they say deprecated with no replacement.

I only found this thread because I am trying to find out more about these. Does anyone suppose there is an update? The warnings state that these will be removed on or after 2011-11-01. The time has come and gone now.

You can safely ignore those errors.

For now you can install gems by specifying gem install rails --no-ri --no-rdoc to install Rails without those errors.

And in the future, you could add:

gem: --no-ri --no-rdoc

to your ~/.gemrc file, to globally ignore documentation for future gem installs.

Also, if you're just getting started I would recommend using a ruby version manager such as rvm or rbenv. It makes life so much easier when managing different ruby versions and gemsets.
