title: SyntaxError: Unexpected token import on v6
body: <p>Iam receiving SyntaxError: Unexpected token import even if my node is v6.
  What am I missing ? How do I make import Construct from 'can/construct/'; work for me instead of require ?</p>
  
  <pre><code>import Construct from 'can/construct/';  // Doesnt work
  var Construct = require('can-construct'); // Works for me
  
  
  var Animal = Construct.extend({
      sayHi: function(){
          console.log("hi")
      }
  });
  
  var animal = new Animal()
  animal.sayHi();
  </code></pre>
  
  <p>I understand I need to be in ES6 to use import statement. But I already have it .</p>
  
  <pre><code>/usr/local/bin/node --version
  v6.10.1
  </code></pre>
  
  <p>not sure package.json matters :</p>
  
  <pre><code>{
    "name": "canjstest",
    "version": "1.0.0",
    "description": "",
    "main": "canjs.js",
    "scripts": {
      "test": "echo \"Error: no test specified\" &amp;&amp; exit 1"
    },
    "author": "",
    "license": "Test",
    "dependencies": {
      "canjs": "^2.2.0"
    }
  }
  </code></pre>
  
  <p>What am I missing ?</p>
