I know it's possible to install a gem without the documentation, but unfortunately, I didn't for the first three months I used ruby. In that time, I managed to install a significant amount of gems, but not once since I started using ruby have I used the documentation on my computer. I always look to docs on the internet.
What is the best way to safely remove the documentation from my computer? Also, is there a way to configure ruby to not install documentation by default?

When you use the --user-install option, RubyGems will install the gems to a directory inside your home directory, something like ~/. gem/ruby/1.9.
Since your goal is to verify a gem is installed with the correct version, use gem list . You can limit to the specific gem by using gem list data_mapper . To verify that it's installed and working, you'll have to try to require the gem and then use it in your code.
run this command:
rm -r "$(gem env gemdir)"/doc/* on windows if you use cygwin
