How to update rails offline?

Question

Is there a way to update Rails in a pc without internet connection?

It has Windows XP, if that matter.

Answer 1

You can download the necessary gems from a computer with internet access, transfer these to the computer you wish to update, and use "gem install ..." to install them.

There are instructions here: http://angrys0ul.com/blog/2007/04/25/how-to-install-ruby-on-rails-on-a-windows-pc/

Another option might be to run Rails off a portable external hard drive (or flash drive) that can be moved from one PC to another. There are a couple of packages, Instant Rails, and Flash Rails, that allow you to have a portable version of Rails on Windows. Unfortunately they are both a bit out of date as far as Rails versions, so you'll still have some upgrading to do once you install them. See Portable Ruby on Rails environment.
