Rails installation error

Rails
1

I have installed Ruby 1.8.7 and rails 3.0.3 on ubuntu 10.04.
i am following the steps given in the book ‘Agile web development with
rails’ and i am new to the world of ruby on rails.

just after entire installation i have created a rails application called
‘demo’

however when i enter the command …ruby script/server i get
the
following error:
Could not find gem ‘sqlite3-ruby (>= 0, runtime)’ in any of the gem
sources
listed in your Gemfile.
Try running bundle install.

I have already installed mysql database.

Thanks,
Chinmaya Joshi

Hi,

By default Rails will work well with embeded sqlite3 database.

so simple run
bundle install
it will solve your problem.

In case you want to work with mysql. You need to add “gem mysql” in the
Gemfile. And then run “bundle install”
Also you may need to change the database config file.

Thanks!

That is because you are using a Rails 2.3 book with Rails 3. You want
edition 4 of the book, or use the tutorial at railstutorial.org.
