Hi,

You should really take look to RVM(Ruby Version Manager) it's awesome!

+1 IMHO RVM will save you a LOT of pain and tears, and it's a piece of cake to setup and start using.

RVM is for managing Ruby, not Rails. How does this help?

managing rails with gemsets http://rvm.beginrescueend.com/gemsets/basics/

Interesting, but seems like overkill. If your application specifies the rails version, it will automatically use that gem.

From the article: "If you have already Rails 2.3.5 and you install the new 2.3.8 you will lost the previous version" - That's not true. You can have multiple versions of Rails (or any gem) installed at the same time and you can use any of them since your application specifies the gems needed, not RVM.

Answer 2

A:

You should be able to do this without needing to uninstall anything. You can specify the version of rails you want to create an application for by typing the following when creating a new app.

rails _2.2.2_ app_name
