title: Downgrade ruby version in windows
body: <p>I am using windows. When I type <code>ruby -v</code> I get: <code>ruby 2.6.6p146 (2020-03-31 revision 67876) [x64-mingw32]</code></p>
  
  <p>I want to downgrade the ruby version to 2.2.3 how can I do that?</p>
  
  <p>As mysql2 gem works on ruby version &lt; 2.6.</p>
