If you installed rubygem with some sore of package management system, it probably provides for an uninstall capability. If not, here is one way to remove it.
- Find out where ruby installs its libraries. If you don’t know where your libraries are located, you can execute the following command:
ruby -e ‘puts $:’
On my machine, this outputs:
- Change into the /usr/lib/ruby/site_ruby/1.8 directory. In there you should find the following files that belong to rubygems:
You should also see the directory "rubygems"
Remove these files and the directory with the following commands:
rm -r gemconfigure.rb rubygems.rb ubygems.rb rubygems
- In order to remove all the gems on your computer, remove the gems directory under /usr/lib/ruby with the following command:
rm -r /usr/lib/ruby/gems
If your ruby libraries are installed somewhere other than /usr/lib/ruby, make the appropriate changes to the above commands.
