Installing ferret

Ruby Apps Ferret
1

I am trying to test drive ferret on a ubuntu dapper installation.

I have a ferret-test.rb file like:
----begin---------
require ‘ferret’
include Ferret
index = Index::Index.new(:path => ‘/opt/search-index’)
----end-----------

When i issue: ruby ferret-test.rb, I get:

ferret-test.rb:1:in `require’: no such file to load – ferret
(LoadError)
from ferret-test.rb:1

How do I resolve this issue? What am I missing?

This is how i had installed ferret:

sudo gem install ferret

I get:

require ‘rubygems’

should work.

Any ideas?

Yes, you have a file called ferret.rb in your current directory which
is being loaded instead of the Ferret gem. Try renaming the file and
everything should work again.

Cheers,
Dave

This is wierd:

I had the above app working fine for a day and just got back to it today
and get an error.

Here is the code from f.rb:

require ‘rubygems’
require ‘ferret’
include Ferret
index = Index::Index.new(:path => ‘/opt/search-index’)

Exception thrown:

./ferret.rb:3: uninitialized constant Ferret (NameError)
from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require’
from f.rb:2

Any ideas?
