Rubygems

As with most programming languages, Ruby leverages rubygems wide set of third-party libraries, rubygems, rubygems. Nearly all of these libraries are released in the form of a gema packaged library or application that can be installed with a tool called RubyGems. RubyGems is a Ruby packaging system designed to facilitate the creation, sharing and installation of libraries in some ways, it is a distribution packaging system similar to, say, apt-getbut targeted at Ruby rubygems. Ruby comes with RubyGems by default since version 1.

Ruby , RubyGems and Bundler can be a bit of an intertwined mess -- it can be hard to tell what magic incantation will tell you what went wrong and how to fix it. The secret is that they're three separate layers. Ruby was originally designed without RubyGems. RubyGems is a separate layer on top with a few seams where it was designed to be detached. Bundler was created for Rails 3. In other words, it makes sense to learn them separately even if you'll only use them together.

A package also known as a library contains a set of functionality that can be invoked by a Ruby program, such as reading and parsing an XML file. We call these packages "gems" and RubyGems is a tool to install, create, manage and load these packages in your Ruby environment. RubyGems is also a client for RubyGems. See our guide on publishing a Gem at guides. Installing and managing a Gem is done through the gem command. For more information about how to use RubyGems, see our RubyGems basics guide at guides. RubyGems is already installed in your Ruby environment, you can check the version you have installed by running gem --version in your terminal emulator. It's better to use a Ruby Version Manager, such as rbenv or chruby. If you still want to use the version provided by your OS package manager, please also use your OS package manager to upgrade rubygems, and disregard any other installation instructions given below.

RubyGems uses rdoc for documentation.

RubyGems is a package manager for the Ruby programming language that provides a standard format for distributing Ruby programs and libraries in a self-contained format called a "gem" , a tool designed to easily manage the installation of gems, and a server for distributing them. The interface for RubyGems is a command-line tool called gem which can install and manage libraries the gems. Though it is possible to use a private RubyGems repository , the public repository is most commonly used for gem management. The public repository helps users find gems, resolve dependencies and install them. RubyGems is bundled with the standard Ruby package as of Ruby 1. Also, RubyGems development was moved to GitHub in

What each gem command does, and how to use it. The cert command manages signing keys and certificates for creating signed gems. For further reading on signing gems see ri Gem::Security. The check command can list and repair problems with installed gems and specifications and will clean up gems that have been partially uninstalled. The contents command lists the files in an installed gem. The listing can be given as full file names, file names without the installed directory prefix or only the files that are requireable. The dependency commands lists which other gems a given gem depends on.
