Heroku Push Error: "sprockets-2.0.0.beta.2 in any of the sources"

I'm tryting to push my RoR 3.1.0.beta1 project up to Heroku from my Git repository using the following command as usual: git push heroku master

But I am getting the following error:

-----> Heroku receiving push
-----> Rails app detected
-----> Detected Rails is not set to serve static_assets
       Installing rails3_serve_static_assets... done
-----> Configure Rails 3 to disable x-sendfile

       FAILED: http://devcenter.heroku.com/articles/bundler
 !     Heroku push rejected, failed to install gems via Bundler

My Gemfile has this line: gem 'sprockets', '2.0.0.beta.2'

Sprockets version 2.0.0.beta.2 exists because I've been pulling different versions including this version. Is there something I'm missing here?

Thanks

Looks like this version has been pulled from Rubygems, only beta.12 and beta.13 are listed:

http://rubygems.org/gems/sprockets

So you'd need to get the specific beta.2 branch from the repo, as Thariq suggests.

BUT, I'd probably go for one of the versions listed on rubygems - there must be good a reason why they were pulled ;)

It's not on rubygems because:

You need to figure out what source you are getting the gem from and add that to the top of your gem file like so:

source 'http://rubygems.org'

gem 'rails', '3.0.5'
gem 'sqlite3'
gem 'sprockets', '2.0.0.beta.2'

gem "sprockets", "~> 1.0.2" is on ruby gems. But you will need to find where your versions is specifically hosted such as http://mysite.org add that to the top of your gemfile.

Presumably you've been pulling from the Sprockets Git Repo. You need to tell your Gemfile where you get a gem that's not in rubygems, so in this case you would use:

gem 'sprockets', '2.0.0.beta.2', :git => 'git://github.com/sstephenson/sprockets.git'
