通过script标签引入，找不到AraleQRCode

[killernova]

如题，根据文件结构引入<script type=:text/javascript src="../dist/arale-qrcode/3.0.5/index.js"></script>,

<script type="text/javascript">

    var qrnode = new AraleQRCode({
      render: 'canvas',
      correctLevel: 0,
      text: 'http://www.alipay.com/',
      size: 300,
      background: '#eeeeee',
      foreground: '#667766',
      pdground: '#00aaee',
      image : 'http://img0.bdstatic.com/img/image/shouye/touxiang1109.jpg',
      imageSize : 100
    });
    document.getElementById('qrcodeCanvas').appendChild(qrnode);
  </script>

提示找不到 AraleQRCode
