What does "No binary rubies available" mean? : <p>Whenever I use <code>rvm install x.x.x</code>, I get this warning even in successful installation:</p>

<pre><code>No binary rubies available for: osx/10.12/x86_64/ruby-2.4.0.
Continuing with compilation. Please read 'rvm help mount' to get more
information on binary rubies.
</code></pre>

<p>I tried to read <code>rvm help mount</code>, but it was beyond the scope of my knowledge. </p>

<p>Can someone explain this warning in simple English? Thanks!</p>
