我正在尝试使用Google Maps API v3,但我总是出错

我在页面中添加了脚本:

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false&libraries=drawing"></script>

我已经实施了:

var drawingManager = new google.maps.drawing.DrawingManager({
      drawingMode: google.maps.drawing.OverlayType.MARKER,
      drawingControl: true,
      drawingControlOptions: {
        position: google.maps.ControlPosition.TOP_CENTER,
        drawingModes: [google.maps.drawing.OverlayType.MARKER, google.maps.drawing.OverlayType.CIRCLE]
      },
      /*markerOptions: {
        icon: new google.maps.MarkerImage('http://www.example.com/icon.png')
      },*/
      circleOptions: {
        fillColor: '#ffff00',
        fillOpacity: 1,
        strokeWeight: 5,
        clickable: false,
        zIndex: 1,
        editable: true
      }

我总是得到同样的错误:

未捕获的TypeError:无法读取未定义的属性"DrawingManager"
