Dependency Error:

[Duncan Stuart]

I've just updated Octopress for the first time in a long time, and on running bundle install I got the following error:

Bundler could not find compatible versions for gem "sass":
  In Gemfile:
    compass (~> 1.0.1) ruby depends on
      sass (< 3.5, >= 3.3.13) ruby

    sass-globbing (~> 1.0.0) ruby depends on
      sass (3.2.19)

Calling bundle update on any of these three gems fixes this, but updates my Gemfile.lock.

I guess this is something which should be fixed at the source, but I'm not sure how. Perhaps a more up-to-date Gemfile.lock? or having more strict dependencies?

i don't see any Gemfile.lock file in the project repository, also i tried to fork, bundle install it and the output didn't produce any errors, is there something i'm missing or didn't get it ?

I see that Gemfile.lock is now in .gitignore. I removed it from my local repo and ran 'bundle install' to install the current versions. Then ran "bundle clean --force" to remove the other fluff.

Apologies - I should have closed this ages ago. I had read the thread explaining why Gemfile.lock isn't under version control but forgot to close this.

On a side note, I'm definitely in the camp that thinks that Gemfile.lock should be checked in, but it seems like the decision has been made a long time ago and I doubt it will be changed.
