Angular-CLI ng new: "Error: EPERM: operation not permitted..." : <p>I am trying to use Angular-CLI to install a new Angular2 app, but keep running into the following issue:</p>

<p><code>ng new payment-calc-app</code></p>

<p>After "Installing packages for tooling via npm", I get the following Error codes:</p>

<p>I've tried <code>npm clean cache</code> and running Command Prompt as an Administrator (I'm on Windows) to no avail. </p>

<p>Oddly enough, when I go to try to delete the folders that the failed installation created, Windows prevents me from deleting them, saying I need to be an Administrator to delete them, even though I am an administrator. I need to go into each individual folder and delete each individual file one at a time.</p>
