gem customizations

Question

I added some caching functionality to the geokit gem and used gemcutter to create a copy 'badnaam-geokit'. The only changed are in Geocoders.rb which works fine if I just modify it locally.

However, after I published it to rubygems and installed it and require it as 'badnaam-geokit' in my environment.rb (config.gem "badnaam-geokit") file I get a nasty.

Any ideas?

Here is the my fork on github

http://github.com/badnaam/geokit-gem

and here is the gem. http://rubygems.org/gems/badnaam-geokit

no such file to load -- badnaam-geokit

Answer 1

While your gem has changed names, the library name has not changed. Your config.gem line is telling Rails to load the gem and then require 'badnaam-geokit' but there's no file in your gem by that name.

The fix this, use the :lib option to config.gem:

config.gem 'badnaam-geokit', :lib => 'geokit'

Furthermore, pushing gems to Rubygems for changes like this is not encouraged. I would instead suggest you switch your Rails project to use Bundler (which works great with Rails 2.3.5) and then use the :git option to load the gem directly from your Github fork.

I used the :lib option.

So this is what worked

config.gem "badnaam-geokit", :lib => "geokit"
