I've just installed a new vm (VirtualBox) with Ubuntu 10.4 and Ruby1.9.1. I've got the package for RUbyGems1.9.1 but when I do gem --version I still get 1.3.5.

To upgrade a gem to a specific version for a Ruby application, do the following steps: Open the Gemfile. Specify the version number in front of the gem. Run bundle install .
Open up the 'Software Center' app from your launcher and type in `RubyGems` without quotes into the application search box at the top right, and press [enter]. RubyGems then can be installed by just clicking on the button labeled 'Install', thats it.
If this is the case, you can look on /usr/lib/ruby/gems/1.8/gems/rubygems-update-x.x.x and take the directory with the highest value of x.x.x.
I got it working using
gem install rubygems-update cd /var/lib/gems/1.9.1/bin sudo ./update_rubygems If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
