所以，几天前我寻求帮助并解决了问题，但是问题又在我制作了第二个模块并开始导入和导出时又返回了，有帮助吗？

<script type='module/javascript' src='main.js'></script>
<script type='module/javascript' src='classes/player.js'></script>

</html>
player.js：
import { Player } from 'classes/player.js';
var canvas = document.getElementById("canvas"),
c = canvas.getContext("2d"),
width = canvas.width,
height = canvas.height;
c.scale(1, -1);
c.translate(0, -width);
