<div class="content wysiwyg-content">
I have an application which was built on a 2.3.5 rails platform.<br />
<br />
Runs through normally with 2.3.8 as well.<br />
<br />
I have a new Windows server which I've installed ruby 1.9.2p0 and then did a gem install rails.<br />
<br />
It installed the rails v3.0. I then went to install rails -v=2.3.5 so that I can run the application.<br />
<br />
However, when I ran rake db:migrate, it gave the error saying that 3.0 is already activated therefore it can't run.<br />
<br />
I'd like to ensure that my application runs.<br />
<br />
Can someone help me on what I need to do. I can't run ruby script/server nor any rake commands...<br />
<br />
I need this to run on Windows due to some constraints that I have.<br />
<br />
Thanks

Ruby is an open-source dynamic object-oriented interpreted language that supports multiple programming frameworks including functional, object oriented and imperative. It also has a dynamic type system and automatic memory management. Ruby focuses on simplicity and productivity. Ruby's market share spiked due to Ruby on Rails, a model-view-controller (MVC) framework for building web applications.

Ruby

A web application framework (WAF) is a software framework that is designed to support the development of dynamic websites, web applications, web services and web resources. The framework aims to alleviate the overhead associated with common activities performed in web development. Most common web application frameworks are defined by specific subsets, including ASP.NET, JaveEE, Symfony, ColdFusion Language (CFML), Laravel, jQuery and AngularJS, or for the related languages, including .NET, PHP, JavaScript, Java, Perl, Python, Ruby, C++ and C.
