How do I update rubygems on the Ruby on Rails droplet image?
The Ruby on Rails image seems to be using rvm to handle Ruby. All fine and good.
I need to install ZenTest 4.7.0 which requires a high version of rubygems... But running
gem update --system doesn't seem to be doing the right thing. As much as it tells me the latest (2.4.1) is installed, when I run "gem install ZenTest -v 4.7.0", I get a complaint that I'm using an old version of Rubygems.
What's going on - how can I successfully install ZenTest?
