How do I install and target a specific version of Nitrous.io?

Question

Just a quick question using nitrous.io. Been following a tutorial on treehouse for ruby on rails, now as they use version 3.2 and I was using 4 it just was impossible to follow.

So, how do I choose which version of Nitrous.io I'm installing / targeting? I need to be using 3.2.

Answer 1

One quick and easy way to handle this would be to install Rails 3.2 alongside with Rails 4.

gem install rails -v 3.2

From there, you can create a new project with Rails 3.2 with the following command:

gem _3.2_ new appname

If you are working on an existing project, ensure your Gemfile is specifying gem 'rails', '3.2.0', and from there you can run bundle install to ensure all dependencies have been installed.
