The gemspec file defines a Gem::Specification object.

A gem consists of two things:

  1. some code
  2. a gemspec file

The gemspec file defines a Gem::Specification object. It contains the required information for a gem. Starting in RubyGems 2.0, a Specification can hold arbitrary metadata.

REQUIRED GEMSPEC ATTRIBUTES

  • author=
  • authors=
  • files
  • name
  • platform=
  • require_paths=
  • rubygems_version
  • summary
  • version

Apart from the list, there are some more attributes that can be included in the gemspec file. These attributes are optional. Some of them are license=, description etc.
