Problem with creating a sample application

Hi Community,

I’m new to rails. I was trying to install and run a sample ruby on
rails application with database as mysql.
I have followed the steps for the installation. However when I start
the “rails server” I get the below error.
“Could not find gem ‘mysql2 (>= 0)’ in any of the gem sources listed
in your Gemfile.”

I have the below version and application installed.
ruby => 1.8.7
rails => 3.0.7 libraries
gem =>1.8.2

My Gemfile looks as below. As per a suggestion in a website I have
tried mysql 2.8.1 and changed in the yaml file still it didnot work
adapter: mysql
encoding: utf8
reconnect: false
database: myapp_development
pool: 5
username: root
socket: /var/run/mysqld/mysqld.sock
gem ‘rails’, ‘3.0.7’

gem ‘mysql2’
#gem ‘mysql’, ‘2.8.1’


can you please help me ?

have you run bundle install?


gem list --local

to be able to see if the mysql gem is actually installed or not.

if not the bundle install should install it for you and you should then
be able to proceed.
