Just rerun (works for gem v1.8.23):

gem install your_gem_name --rdoc

I tried this and it looked like it worked (e.g. the rdoc option became clickable in the web page served up by gem server), however, clicking on it just resulted in an error page. As it turns out, I had --no-ri set because I don't use RI documentation, but apparently when you try to view RDOCs via gem server, they look for a cache.ri file and through an exception if they can't find it. .... So short story, if you're going to do this make sure you generate RI docs too . gem install your_gem_name --rdoc --ri – Steven Chanin Feb 06 '14 at 18:49
