I bundle update'd to Rails 4.0 by accidents, how to undo?

bundle, ruby, ruby-on-rails, ruby-on-rails-3.2, ruby-on-rails-4

Solution

yes you can simple delete the gemfile.lock and re-bundle install, or, add version number to rails and then do

bundle update.

Problem

I had the following near the top of my Gemfile: ``` gem 'rails' ``` I'm using rails 3.2.x and now when I ran `bundle update`, I got upgraded to rails 4.0 which I'm not ready for yet. Can I simply delete my Gemfile.lock file, add the version number to `gem 'rails'` in my Gemfile and re-`bundle install`?
