想使用vscode创建一个cesium地球，点击open with default browser后出现如下问题
代码如下
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<script src="E:\cesiumjs\1\1.1\lib\Cesium\Cesium.js"></script>
<link href="E:\cesiumjs\1\1.1\lib\Cesium\Widgets\widgets.css" rel="stylesheet">
<style>
body{
margin:0px;
}
#cesiumContainer {
width: 100%;
height: 100%;
}
</style>
</head>
<body>
<div id="cesiumContainer"></div>
<script>
Cesium.Ion.defaultAccessToken =
'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqdGkiOiI2YjhjNjc5MS02MGUyLTRlM2UtODQxZS1mZTE0NzZhYTZlZWIiLCJpZCI6MTM3MTM0LCJpYXQiOjE2ODM1MTYxNjB9.RWL4gXhJuDco42chGEsy_SRZqeoYG8-WDgMoM7MoHzQ';
var viewer = new Cesium.Viewer('cesiumContainer');
//viewer.scene.debugShowFramesPerSecond = true; //显示帧率
</script>
</body>
</html>
请问如何解决？
