Hi,  
I am constantly getting an error when I use the rake command to do a  
migration or even use drop, this happened after I installed some  
plugins such as paperclip and seed-fu.

The error is:  
rake aborted!  
uninitialized constant PKG\_NAME  
/var/www/html/quote/Rakefile:10

The Rakefile looks like this:

# Add your own tasks in files placed in lib/tasks ending in .rake,

# for example lib/tasks/capistrano.rake, and they will automatically

be available to Rake.

require(File.join(File.dirname( **FILE** ), ‘config’, ‘boot’))

require ‘rake’  
require ‘rake/testtask’  
require ‘rake/rdoctask’

require ‘tasks/rails’ \<==Line 10

I also ran with trace option and see:

(in /var/www/html/quote)

Look for where this PKG\_NAME constant is being used and why it isn’t  
initialized.

It seems to be referencing the addressable plugin, after I removed it,  
rake worked fine.
