# Description:

Fixes #2686.

When the default bundler gem was being installed through `gem update --system`, the proper rubygems wrapper was not being generated. This PR fixes that, and also adds missing wrapper support for `gem install --default` in general.

# Tasks:

RubyGems Travis Build Status Appveyor Build Status Maintainability

RubyGems is a package management framework for Ruby.

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, a public repository of Gems that allows you to publish a Gem that can be shared and used by other developers. See our guide on publishing a Gem at

Getting Started

Installing and managing a Gem is done through the gem command. To install a Gem such as Nokogiri which lets you read and parse XML in Ruby:

$ gem install nokogiri

RubyGems will download the Nokogiri Gem from and install it into your Ruby environment.

Finally, inside your Ruby program, load the Nokogiri gem and start parsing your XML:

require 'nokogiri'

Nokogiri.XML('<h1>Hello World</h1>')

For more information about how to use RubyGems, see our RubyGems basics guide at


RubyGems is likely already installed in your Ruby environment, you can check by running gem --version in your terminal emulator. In some cases your OS's package manager may install RubyGems as a separate package from Ruby. It's recommended to check with your OS's package manager before installing RubyGems manually.

If you would like to manually install RubyGems:

  • Download from, unpack, and cd into RubyGems' src
  • OR clone this repository and cd into the repository (make sure to run git submodule update --init)

Install RubyGems by running:

$ ruby setup.rb

Note: You may need to run the install script with admin/root privileges.

For more details and other options, see:

$ ruby setup.rb --help

Upgrading RubyGems

To upgrade to the latest RubyGems, run:

$ gem update --system

Note: You might need to run the command as an administrator or root user.

See UPGRADING for more details and alternative instructions.


RubyGems uses rdoc for documentation. A compiled set of the docs can be viewed online at rubydoc.

RubyGems also provides a comprehensive set of guides which covers numerous topics such as creating a new gem, security practices and other resources at
