Problem creating Hello World app in Ruby on Rails

rubyonrails-talk
1

Hi All,

I just installed Ruby on Rails on my MacBook Pro and tried to create the Hello World app that is documented in the Agile Development with Rails book. I followed all the instructions for creating the Hello World app but get the following error when I try to load http://localhost:3000/say/hello

MissingSourceFile in SayController#index

no such file to load -- sqlite3

Can anyone please let me know what I need to do to fix this issue? Thanks!

P.S., I have the following things installed on my MacBook Pro:

1. Ruby 1.8.6 2. Rails 2.1.2 3. MySQL 5.0.67

If you want to use mysql, then set up your rails project like this: % rails --database=mysql <name> If you leave out the database option, rails will assume you want sqlite3. (I think mysql used to be the default some time ago).

You can alter the database and connection settings in config/ database.yaml.

its looking sqlite3 database which is not installed on your mac.

get the binary for mac from here SQLite Download Page

install it and then run sudo gem install sqlite3-ruby

and you should be ok to go.

Otherwise if you want to use mysql then change your database.yml file in the config directory like so (and remove all config options for sqlite3)

development:   adapter: mysql   database: db_name   username: root   password:   host: localhost   encoding: utf8

do this for test and production as well
