Question

I have a RAILS plugin for coffeescript testing

https://github.com/bradphelan/jasminerice

with a gemspec defined as

# Provide a simple gemspec so you can easily use your
# project in your rails apps through git.
Gem::Specification.new do |s|
  s.name        = "jasminerice"
  s.summary     = "Pain free coffeescript unit testing for Rails 3.1 using jasmine"
  s.description = "Full support for the Rails 3.1 asset pipeline when bdd'ing your coffeescript or javascript using jasmine"
  s.files       = `git ls-files`.split "\n"
  s.authors     = ["Brad Phelan"]
  s.version     = "0.0.6"
  s.platform    = Gem::Platform::RUBY
  s.add_dependency( 'haml' )
end

At the bottom I have added the haml dependency. If jasminerice is included in the client Gemfile as

gem 'jasminerice'

then it fails because ‘haml’ is not included. If haml is included explicity as

gem 'jasminerice'
gem 'haml'

then all is ok. This doesn’t mesh with my understanding of Gemfiles and gemspecs. Is there something obvious I have missed.

Answer 1

I think you’re missing a gemspec line in your gems Gemfile.

From http://yehudakatz.com/2010/12/16/clarifying-the-roles-of-the-gemspec-and-gemfile/ :

When developing a gem, use the gemspec method in your Gemfile to avoid duplication. In general, a gem’s Gemfile should contain the Rubygems source and a single gemspec line.
