title: Aurelia build fails - cannot find module babel-runtime
body: <p>I created an <a href="https://github.com/aurelia/cli/issues/443" rel="nofollow noreferrer">issue</a> at the Aurelia CLI repo, but figured I would ask here just in case. I'm on Windows 7 with node 7.2.1 and npm 4.0.5. The linked issue has details about dependency versions.</p>
  
  <p>When I try to build via <code>au build</code> I get the error below. I have tried starting from scratch:</p>
  
  <ol>
  <li>Install latest node version using <a href="https://github.com/coreybutler/nvm-windows" rel="nofollow noreferrer">nvm</a> (node 7.2.1)</li>
  <li><code>npm install npm -g</code> (npm@4.0.5)</li>
  <li><code>npm install aurelia-cli -g</code> (aurelia-cli@0.23.0)</li>
  <li><code>npm install</code></li>
  <li><code>au build</code></li>
  </ol>
  
  
  
  <pre><code>&gt; au build

  <p>I tried <code>npm install babel-runtime</code> explicitly, but that does not work.</p>
