New Ruby on Rails developer needs help setting up a development environment

I've been experimenting with Rails a lot lately, and have made progress. I set up my environment on Windows 7 according to http://ruby.railstutorial.org/, and made sure it works with the example code. Now I want to run a project from Github that I downloaded, but doing a bundle install produced errors开发者_如何学编程 on my machine (specifically github erros). How close do I need to duplicate the original developers environment? Kind of confused about how portable these apps are across platforms/servers, etc.

Here are the specs on apps original development environment if it helps:

-Ruby 1.9.2, Rails 3.0.3, and MySQL 5.1.

-Ubuntu 10.04,Nginx, postfix, other dependencies installed like Sphinx (full text search engine) and ImageMagic (auto resize images & thumbnails).

Here is the error:

Fetching git://github.com/mislav/will_paginate.git

Git error: command `git clone 'git://github.com/mislav/will_paginate.git' "C:/Ra

Thanks.

Try the solution here, error: "fatal: I don't handle protocol ``git` when using bundle install

If you don't need will_paginate's repo head you can always change

gem 'will_paginate', :git => "git://github.com/mislav/will_paginate.git"

To just

gem 'will_paginate'
