Error in rails at startup

Rails
1

Hi everybody.
I met a strange situation when I begin to use rails.
I install the ruby 1.86, rails 2.0.2, and update the gem to 1.0.1
then I install mongrel.
Just create the rails project and type
“ruby script/generate controller Greeting”
then edit the file greeting_controller.rb add several lines
def index
render :text => “

Welcome to your first Rails application

”
end

Now I get in this url. It says
MissingSourceFile (no such file to load – sqlite3):
E:/Program
Files/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
gem_original_require' E:/Program Files/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:inrequire’
E:/Program Files/Ruby/lib/ruby/gems/1.8/gems/activesupport-
2.0.2/lib/active_support/dependencies.rb:496:in `require’

and so on.
Who can tell me how to fix it .Thanks

your rails database.yml is configured to use sqlite3,
most likely you installed mysql (or not, or nothing)

in config/database.yml
this:

development:
adapter: mysql
encoding: utf8
database: myapp_dev
username: root
password:
test:
adapter: mysql
encoding: utf8
database: myapp_tesst
username: root
password:
production:
adapter: mysql
encoding: utf8
database: myapp_prod
username:
password:

would be correct for mysql

OMG, it works!
I am so appreciative of this and can’t hold myself!

Install sqlite3.
