What’s the name of the Ruby application packaging utility and how do you install Rails with it?
In what instances would you avoid WEBrick?
Why should you install a particular version of Ruby on your platform when Ruby already comes installed?
RubyGems, or just “gems,” which is run with the
gem command, is Ruby’s application packager. To
install the latest version of Rails and all its dependencies, just type
gem install rails.
WEBrick is great for testing your Rails applications, but definitely not the best choice for deployments where performance matters.
