Error install travis - minitest requires Ruby version < 4.0, >= 2.6. The current ruby version is 2.5.0

Here I am not able to install travis with Ruby version 2.5.0

The installation here https://github.com/travis-ci/travis.rb#installation instructs Make sure you have at least [Ruby](http://www.ruby-lang.org/en/downloads/) 2.3.0
