vagrant-aws plugin installation error
<p>I am trying to install the aws plugin for vagrant but getting an error.  I am running vagrant 1.9 on macOS Sierra 10.12.1.  I have no ruby expertise so I can use all the help you can provide.<br>
I tried installing ruby version 2.3.3, but based on the paths below vagrant is using the embedded version.</p>

<pre><code>vagrant plugin install vagrant-aws
