Ajj. Working with Ruby and the gem for installing sqlite database fails.
I tried to download sqlite3, and run the install gem command:

D:\>gem install sqlite3-ruby

Building native extensions.  This could take a while...ERROR:  Error installing sqlite3-ruby:        ERROR: Failed to build gem native extension.c:/ruby/bin/ruby.exe extconf.rb install sqlite3-ruby --platform Win32checking for fdatasync() in rt.lib... nochecking for sqlite3.h... nonmake'nmake' is not recognized as an internal or external command,operable program or batch file.Gem files will remain installed in c:/ruby/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.4 for inspection.Results logged to c:/ruby/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.4/ext/sqlite3_api/gem_make.out

This is because not all versions of sqlite3 are windows versions.
Fine, and now?
You can list all available sqlite gems:

D:\>gem list --remote --all sqlite

*** REMOTE GEMS ***

sqlite (2.0.1, 2.0.0, 1.3.1, 1.3.0, 1.2.9.1, 1.2.0, 1.1.3, 1.1.2, 1.1.1, 1.1)
sqlite-ruby (2.2.3, 2.2.2, 2.2.1, 2.2.0, 2.1.0, 2.0.3, 2.0.2)
sqlite3-ruby (1.2.4, 1.2.3, 1.2.2, 1.2.1, 1.2.0, 1.1.0, 1.0.1, 1.0.0, 0.9.0, 0.6
.0, 0.5.0)
sqlitecache (0.0.1)

Then, you can easily install the version you need:

D:\>gem install sqlite3-ruby -v 1.2.3
Successfully installed sqlite3-ruby-1.2.3-x86-mswin32
1 gem installed
Installing ri documentation for sqlite3-ruby-1.2.3-x86-mswin32...
Installing RDoc documentation for sqlite3-ruby-1.2.3-x86-mswin32...

Just type in the command line (don’t worry it can take a while):

 gem install rails --include-dependencies

This will auto install Rails with some documentation.
Now let’s start to create a Rails workfolder.

I want it something like this:
testProject
-app
-config
-db
-doc
-lib
-log
-public
-script
-test
-temp
-vendor
..README
..RakeFile

 rails testProject

Done!

To install sqlite3 (database) for Ruby, just type:

 gem install sqlite3-ruby --version 1.2.3

Creating a sqlite database is easy as well:

 rake db:create:all
 ruby script\generate scaffold user first_name:string last_name:string address:text
 rake db:migrate

Now prefill this database with values:

ruby script\console
lee = User.create(:first_name => 'lee', :last_name => 'boonstra', :address => 'Holland')

Do you want a more graphical tool, to view your database or run your queries? Use SQLiteManager.

To install gems for debugging ruby code (in for example Aptana):

 gem install ruby-debug-ide

To install gems for Mongrel HTTP server:

 gem install mongrel

Do you understand now, why developers love Ruby? It’s so handy and easy.
And I know more fun! Let’s create a Ruby webserver! (Again via the command line).

ruby script/server

Your webserver will be start, by default on port 3000.
Do you want a default port? Let’s say 8000?

ruby script/server -p 8000

Now go head! Let’s run your server: http://localhost:3000

Let’s start programming with Ruby. Cause what I’ve read about it, it should be fast, easy and fun.
You can download ruby from: rubyforge.org.
I installed the windows version. To see if it’s correctly installed go to your command line:

  ruby -v

This is what the command line tells me, what is installed:

ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-mswin32]

Now create a new folder (structure) for your ruby (.rb) files.
Let’s start with the famous Hello World example, to print a string:

hello_world.rb:

puts "Hello World!"

Run this example in the commandline:

 ruby hello_world.rb

And your done!

 Hello World!
