Possible to force version of dependent gem?

Question

I'm using two gems that depend on the faraday gem. Unfortunately, the depend on different versions...

Bundler could not find compatible versions for gem "faraday":
  In Gemfile:
    vacuum (~> 0.2) depends on
      faraday (~> 0.7.6)

    sorcery depends on
      faraday (0.8.1)

Is there a way to force vacuum to use the version of faraday that sorcery depends on?

Answer 1

The master branch depends on faraday 0.8.1. Point your Gemfile at the git repo for now, and urge the author to release an updated gem to rubygems.

To answer your question for the case where the author hasn't updated, you'd have to fork the gem yourself, update the dependency in the gemspec, and use your forked version in your app.
