How to uninstall gem specific documentation post installation

I just installed the engineyard gem and would like to know how to uninstall all ri / RDoc documentation of engineyard post installation

Is it safe to remove all files from the following folder c:\Ruby192\lib\ruby\gems\1.9.1\doc

c:\Ruby192\bin>gem install engineyard

I haven't had any experience with that gem yet, but I hope this can help you to track your rdoc and ri doc path.

gem env

on my Mac system, I found this path from INSTALLATION DIRECTORY

/opt/experiment/ruby/lib/ruby/gems/1.9.1/doc/

And when I open it (or explore in Windows) I saw some gems' rdoc/ri doc inside this path. Try to remove your gem's doc there. Let me know if it works, it's working here on my Mac.

Next time when you install rubygems but don't want ri/rdoc installed, remember to type this --no-rdoc --no-ri option when you do gem install something

As a reference comparison I'll just copy paste my gem env here

. gem env
