Ruby gem referencing different versions of same gem

Question

One of my ruby engine( a gem) is having a dependency on one of my other projects. With some issue in other project I have to uplift the dependency version of a gem in my engine. I am getting the following output when running bundle install.

Bundler could not find compatible versions for gem "Gem A":
  In Gemfile:
    My Gem Engine (>= 0) ruby depends on
      Gem A (~> 2.8) ruby

    MyGem Engine (>= 0) ruby depends on
      Gem A (3.0.0.SNAPSHOT.20141016054448)

Answer 1

Updating the rails and ruby version fixed the issue. The dependent gem is having dependency of latest ruby and rails versions.
