Update rails to a specific version

Question

How can I update Rails to a specific version? I have Rails 3.2.2 on my local machine, but I need to update to version 3.2.3.

If I execute gem update rails, it will update to version 3.2.6, which is the latest.

How can I do this?

Answer 1

gem install rails --version=3.2.3

Or use bundler. Write in Gemfile:

gem 'rails', '3.2.3'

and execute in rails root directory

bundle install
