What can cause an error when creating an application in Ruby Rails?

Question

Ruby on Rails

Hello everyone, I recently decided to start learning Ruby Rails.
But as it turned out, I had problems creating the first application.
To work with Ruby, I prepared Linux Mint 17.1 . Installed version of Ruby 1.9.3p484

Rails - 3.2.16 at

Answer 1

Could not find gem 'rails (= 3.2.16) ruby' in the gems available on this
machine. - rails version 3.2.16 is not installed on the computer (and such a version is registered in Gemfile). And you don't have to install them.
Ruby 1.9.3p484 (2013-11-22 version 43786) [i686-Linux]
Rails - 3.2.16
Sand is already falling off them.
Install ruby ​​2.2.0, rails 4.2.1 and learn them from new books/tutorials.

Answer 2

Everything is well described here, and there are 4 rails and 3.2, there is also a setting-installation.
