Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

=============
[<internal:/usr/share/rubygems/rubygems/core_ext/kernel_require.rb>:85:in `require': cannot load such file -- io/console/size (LoadError)]: [Required file,`io/console/size` can not be loaded. This is a constituent part of `io/console` gem.]

Issue: Default gem `io/console` is not present on the build system. This is a serious issue, as it should be packaged with the standard Ruby distribution.
Resolution: Ensure your Ruby installation is valid, ideally reinstalling it entirely after identifying why wasn't a one of default gems present.
