I've tried my first app with RoR in a simple hello world.. and the console displayed:

Status: 500 Internal Server Error   no such file to load -- sqlite3

Install sqlite3.

Or if you are using mysql/postgresql/or what ever db edit config/database.yml and setup things there You can also do like when creating a project like

rails project_name -d mysql

  and if its postgresql

rails project_name -d postgresql

It makes a difference what platform you are on. Since you are building on a Microsoft machine you require a Microsoft development environment. I do not build native MS apps so I do not know if there is a free version of Visual Studio available or not. Nor can I say whether or not it will suffice, even if such a thing exists.

If you are building Rails apps on MS then I really recommend that you install the cygwin environment on your host and do your development there.

Or alternatively install a virtualization product (e.g., xVM, VMWare) with Linux for a more Rails-friendly dev environment.

FWIW,

I always recommend InstantRails for developing RoR on Windows. I found it very easy to install and use, providing a complete environment in one package. I have just switched to a dual boot with Windows and Ubuntu however and that is an even better solution.

What is cygwin? Previously I’m having a hard time in displaying the simple outputs in RoR… But it’s only just the beginning… Thank you for the responses guys, I appreciate it… Have a nice one ahead…

Alternatively, you could take the advise from: Installing sqlite3-ruby on windows not working - Rails - Ruby-Forum

and

gem install sqlite3-ruby -v=1.2.3

Enjoy! Bryan
