errors building rails app

[Rajinder Yadav]

Hello I can't seem to build a rails app, I am getting error with, 'rake
db:create' as well as the general 'rails generate' command?

my linux box environment:

$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]

$ gem -v
1.8.5

$ rails -v
Rails 3.0.9

$ uname -a
Linux karma 2.6.38-10-generic #46-Ubuntu SMP Tue Jun 28 15:07:17 UTC
2011 x86_64 x86_64 x86_64 GNU/Linux

Here is the output for each:

$ rake db:create

You left off the name of the resource to generate and went straight into the field definitions.

$ rails g scaffold <name> title:string description:test
