Questions tagged [bundler]

Bundler is a tool that makes it easier to keep track of what Ruby gems (and what versions of those gems) an application depends upon. It does so by installing all the gems in your application’s Gemfile. Bundler itself is a gem and can be installed with the following: $ gem install bundler

Bundler is a system that attempts to manage a Ruby application's gem dependencies across multiple developers and environments. One can define the required gems for a Ruby application in a Gemfile and then "bundle" those gems and any sub-dependencies with the application, effectively sandboxing the app -- not just to a specific set of gems, but to a specific set of gem versions.
