TL;DR: Use the :path option.

Assuming you want to install a gem from a not reachable resource, such as:

# Gemfile
gem 'rails_admin', :git => 'git://github.com/sferik/rails_admin.git'

and you can't install the gem using bundle install because of a firewall or something.

Following these steps:

1. Download the file (using any approach you can, e.g. using http_proxy, from https://github.com/sferik/rails_admin/zipball/master)

2. Put the downloaded file into a folder, such as vendor/gems/rails_admin, and the file in it should look like:

   $ ls vendor/gems/rails_admin
   app  config  Gemfile  Gemfile31  lib  LICENSE.md  rails_admin.gemspec  Rakefile  README.md  screenshots  spec
   

3. Now let's modify your Gemfile:

   gem 'rails_admin', :path => "vendor/gems/rails_admin"  
   

4. Run bundle, works!
