I don’t know why this is so poorly documented on the web. I guess everyone assumes that it’s so easy, that everyone knows it. Well, I forgot how and spent an hour on the web trying to find out how to start your own rdoc server. Here’s the command for anyone else who might be in my same boat:
$ gem_server









gem_server is now deprecated use
$ gem server
instead.
The gems on Mac 10.5 is too old. Update gems itself with gem update –system
This doesn’t show the RDoc for the ruby core, only gems installed.
$ gem server
worked perfect on my macbook 10.5
