With a great ecosystem, comes great responsibility. Developers which are using older versions should consider upgrading to stay up to date and maintain consistent and coherent Ruby gem install results.īundler-audit and the case for improved Ruby gems security The BUNDLED WITH directive specifies the version of Bundler which was used to create the lockfile. The RUBY VERSION directive is optional and specifies the Ruby runtime version that was used when creating this Gemfile.lock lockfile. ![]() The PLATFORMS directive is an open list of target platforms for which building native Ruby gems is required, due to the cross-compilation chain needed for Ruby extensions written in C, for example. The remote directive instructs the bundler tool where is the source to fetch these Ruby gems for installation. These are identified under the specs directive. The GEM directive starts the block for listing out all the Ruby gem dependencies in a nested tree format which shows direct and transitive dependencies and their versions. Let’s review the specification and format of this gem dependency lockfile: That’s probably the last thing you want happening in an automated CI or build environment, or for the other Ruby developers who collaborate on the project with you.ģ remote : https: /// 4 specs: The above leads to the fact that without a lockfile to pin down the entire nested dependency of Ruby gems installed for your project, you’d be introducing indeterministic versions of installed gems. It could be fetching latest, or just the latest in a semantic version range.Įven if you pin these direct Ruby gem dependencies to hard-coded versions, they could still resolve an unexpected dependent gem version with every new install. These direct Ruby gem dependencies use a sparse and loosely defined version for the package. Only direct Ruby gems dependencies are documented. ![]() If you were solely restricted to defining your dependencies using bundler’s Gemfile package manifest, then you’d be subject to the following constraints: RubyGems is the central package registry where third-party, open source Ruby gems are shared as well as the official Ruby package manager, known as gem when interacted with via the command line interface.Ģbundle install -without development Why do we need a Gemfile.lock? What is RubyGems and how is it different from Bundler? Gems are packaged source code libraries that are modular, independent and are easily reusable across projects. Its source code files are easily recognizable using the. RoR is based on Ruby which is is a dynamic, cross-platform and interpreted based language. You might have heard about Ruby on Rails (RoR), the popular web development framework that contributed a lot to Ruby’s success and popularity. In this article, I'll run through the concepts and tooling that make up the Ruby dependencies ecosystem, and answer some of the common questions Ruby developers have. Hence, attention to detail for how you manage and audit your open source Ruby gems is crucial. Similarly to other open source ecosystems, threat actors may publish deliberate malicious code or such which includes backdoors or credentials harvesting. ![]() These gems are authored by the community, and are available from which is the official registry for Ruby libraries. Ruby, much like other programming languages, has an entire ecosystem of third-party open source libraries which it refers to as gems, or sometimes Ruby gems.
