When I create a new engine in Rails 3.1 stable and then access the dummy
app or the engine I get an error say that the app can’t find jquery.
I’ve created the engine using
rails plugin new coffee --mountable
I’ve also created a basic controller in the engine and the dummy app. If
I remove the javascript include tag, everything works. But with the tag
there it just bails since it can’t fine jQuery. The jquery-rails gem is
installed. I have jquery as a dependency in my
gemspec file. I’ve even added an Gemfile to the dummy app just to try,
but it gives the same error.

Hey Jorgen,
This isn’t a solution, but it may be better to simply remove the line
from your js file (Looks like #= require jquery) and use the Google
CDN version:
= javascript_include_tag
‘//ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js’, :defer
=> true, :async => true
This will this be faster for your users (because Google has more
cloudspace than you, probably) and it also removes the need for
Sprockets to compress it.
I hope you find out what’s going on. 
Cheers

Hi Kurtis,
Thanks for your answer. I was thinking the same thing and I’ll just
start developing without javascript all together since I don’t need it
in the initial phase.
I’ve also tried using and creating the engine with Rails 3.1.0rc5 and
3.1.0rc8 and I get the same error. Surely I can’t be alone with geting
this error?
I think I’ll post an issue on Github.
I thought I would post here very quickly because I was having the same
problem and utilizing the google cloud resolved the issue. Here is what
it looks like now.
// This is a manifest file that’ll be compiled into including all the
files listed below.
// Add new JavaScript/Coffee code in separate files in this directory
and they’ll automatically
// be included in the compiled file accessible from
http://example.com/assets/application.js
// It’s not advisable to add code directly here, but if you do, it’ll
appear at the bottom of the
// the compiled file.
//
//= javascript_include_tag
‘//ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js’, :defer
=> true, :async => true
//= require jquery_ujs
//= require_tree .
I had the same problem and finally fixed.
The solution is to explicitly require the ‘jquery-rails’ gem in the
dummy config/application.rb file, so Sprockets can add the jquery
assets in the assets.path.
In test/dummy/config/application.rb
require File.expand_path('../boot', __FILE__)
# Pick the frameworks you want:
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "rails/test_unit/railtie"
require "sprockets/railtie"
# Auto-require default libraries and those for the current Rails
environment.
Bundler.require :default, Rails.env
require "coffee"
require "jquery-rails" # this should be auto-included with the
Bundler.require :default, Rails.env, but it’s not happening
module Dummy
class Application < Rails::Application
# ...
end
end
Same with other gems that have assets that should be auto-loaded by
Sprockets.
Hope this helps.
The solution for me was to add jquery-rails to my engines Gemfile and
restart the server.
I would suspect that it does not want adding to the gemspec however,
however adding it as a development dependency might be okay.

At the very least it could be a good idea to include in the issue:
It’d be nice to know where Sprockets was looking for the file.

This solved my problem, I gotta login to thank you!
