title: Error installing Sass (Ruby 2.5.0.1, MSYS2 20161025.0.0)
body: <p>I tried to install Sass. I installed <em>Ruby</em> and <em>MSYS2</em> prior to that, the latest from all with <a href="https://chocolatey.org/" rel="nofollow noreferrer">Chocolatey</a>:</p>
  
  <pre><code>choco install ruby
  choco install msys2
  </code></pre>
  
  <p>Seemingly they were properly installed. <code>ruby -v</code> results in:</p>
  
  <pre><code>ruby 2.5.0p0 (2017-12-25 revision 61468) [x64-mingw32]
  </code></pre>
  
  <p>When I tried to run <code>gem install sass</code> I received the following error message:</p>
  
  <pre><code>ERROR:  Error installing sass:
          The last version of ffi (&lt; 2, &gt;= 0.5.0) to support your Ruby &amp; RubyGems was 1.9.18. Try installing it with `gem install ffi -v 1.9.18` and then running the current command again
          ffi requires Ruby version &lt; 2.5, &gt;= 2.0. The current ruby version is 2.5.0.
  </code></pre>
  
  <p>Ok, so I attempted to run <code>gem install ffi -v 1.9.18</code>.</p>
  
  <p>I received this error message:</p>
  
  <pre><code>ERROR:  Error installing ffi:
          The last version of ffi (= 1.9.18) to support your Ruby &amp; RubyGems was 1.9.18. Try installing it with `gem install ffi -v 1.9.18`
          ffi requires Ruby version &lt; 2.5, &gt;= 2.0. The current ruby version is 2.5.0.
  </code></pre>
  
  <p>I tried to reinstall Ruby with proper installer, restarted computer, but the same error appears.</p>
  
  <p><em>How can I make Sass to get installed?</em></p>
