How to install / use Devise in Rails 2.3.5?

Question

I tried installing from v.1.2.oauth branch in Devise on Github, but I still get the error message.

How do I install a development gem on a rails 2.3.5 app? In particular, I need one that works with omniauth

gem install devise -v "1.2" ERROR: Could not find a valid gem 'devise' (= 1.2) in any repository config.gem 'devise', :git => 'http://github.com/plataformatec/devise.git', :branch => 'omniauth' ERROR: Error installing devise: ERROR: Failed to build gem native extension. c:/Ruby187/bin/ruby.exe extconf.rb creating Makefile make 'make' is not recognized as an internal or external command, operable program or batch file. 

Answer 1

Rails 2.3.x support can be found by installing Devise 1.0.x from v1.0.

Answer 2

gem install devise -v = 1.0.7 worked for me.
