Updating a gem that is only a dependency

How do you update a gem that is a dependency but not in my Gemfile? For example, I am receiving a bundler-audit warning that I need to use eventmachine 1.0.4, but it is not in my Gemfile. However it is in my Gemfile lock at version 1.0.3.

Solution

  • My approach was to put the following into my Gemfile

    gem 'eventmachine', '~> 1.0.4', require: false

    then I did bundle update eventmachine. When doing this, I chose the earliest release is needed.

    This fixed the bundler-audit warning and all my tests passed. The require false should mean that eventmachine should only be called when necessary.
