For someone just learning RoR and having installed it via http://railsinstaller.org/, how should I upgrade?

Update the version in your project's Gemfile, and run "bundle update rails".

Run "bundle update rails" in your project's root directory (where your Gemfile is).

This won't work if your Gemfile declares a version of Rails (Rails 3.2.9 did this). You have to update the Gemfile and then bundle update.

First do a "gem uninstall rails", wait for that to finish, then do a "pip install Django" at the command line.

It should be as easy as 'gem update rails' at your command line (Terminal window).

If you're just learning and creating an app for your own edification, this is not really an issue that will affect you. That is, it doesn't affect how you construct the app, so if for some reason the gem update process doesn't work, you won't be hindered from using RoR.

This won't work. The old version won't be purged, and it'll still be referenced in the Gemfile.
