Ruby on Rails Installation Error

Ruby is an open-source dynamic object-oriented interpreted language that supports multiple programming frameworks including functional, object oriented and imperative. It also has a dynamic type system and automatic memory management. Ruby focuses on simplicity and productivity. Ruby's market share spiked due to Ruby on Rails, a model-view-controller (MVC) framework for building web applications.

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.

Installation is the act of making a computer program program ready for execution. Because the process varies programs often come with a specialized program responsible for doing whatever is needed for their installation. Installation may be part of a larger software deployment process. Cross platform installer builders that produce installers for Windows, Mac OS X and Linux include InstallAnywhere, InstallBuilder and Install4J. Installers for Microsoft Windows include Windows Installer, InstallShield, and Wise Installation Studio; free installer-authoring tools include NSIS, IzPack, Clickteam, InnoSetup, InstallSimple and WiX. Mac OS X includes Installer, and also includes a separate software updating application.
