How to test old rails2 application in rails3 environment?

Question

I am learning how to build rails application. And I found a very helpful blog github,
https://github.com/balgarath/video-app

But this project is done 4 years ago.

I trying to follow the instructions to compile it. But I cant run it without the gemfile...

user@user:~/test2/video-app$ bundle exec rake db:migrate
Could not locate Gemfile

user@user:~/test2/video-app$ rake db:create
WARNING: 'require 'rake/rdoctask'' is deprecated.  Please use 'require 'rdoc/task' (in        
RDoc 2.4.2+)' instead.
at /usr/local/lib/ruby/gems/1.9.1/gems/rake-0.9.2.2/lib/rake/rdoctask.rb
rake aborted!
no such file to load -- scrubyt

saasbook@saasbook:~/test2/video-app$ rake gems:install

rake aborted! no such file to load -- scrubyt (See full trace by running task with --trace)

Does anyone know how to run these old applications in my localhost?

I just try to run it and learn from the codes...

Thanks..

It's probably much easier to understand the functionality and adopt it into a new Rails application instead of trying to get it running. You will run into multiple issues like outdated gems, changed APIs and so on.

Good luck.

Btw. you are not compiling any code. Ruby is an interpreted language.
