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:
