Hi there - new to RoR but very excited about it indeed -

I have just manged to install everything.

However, when I browse to http://localhost:3000/ then click the "About
your application’s environment" - from the console I get :

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

Perhaps someone can tell from my configuration what is wrong ??? What I
may be missing ??

My configuration is

    * Mac OSX 10.4.11
    * Ruby - v 1.8.6
    * Rails
    * Mongrel
    * RubyGems 1.3.3
    * MYSQL 5.0.27

database.yml file =

  adapter: mysql
  encoding: utf8
  database: temp_development
  username: root
  socket: /tmp/mysql.sock

# Warning: The database defined as 'test' will be erased and
# re-generated from your development database when you run 'rake'.
# Do not set this db to the same as development or production.
  adapter: mysql
  encoding: utf8
  database: temp_test
  username: root
  socket: /tmp/mysql.sock

  adapter: mysql
  encoding: utf8
  database: temp_production
  username: root
  socket: /tmp/mysql.sock

Many thanks in advance

Does the database exist that you are connecting to?
#> mysqladmin create temp_development

also ensure you have the mysql gem installed (current versions of
rails require the native gem)

#> sudo gem install mysql

lastly make sure your project can communicate with the database
rake db:migrate

If all is well the only thing you should have to do in the future is
ensure the database exists with the mysqladmin command.

looks like you're missing the mysql gem (ruby bindings for the mysql
