我正在尝试 web application bundler parcel 并按照Github描述进行操作。我的 html 和 javascript 文件如下。
我parcel index.html给出以下错误，

索引.html
<!DOCTYPE HTML>
<head>
<title>Add two numbers</title>
<script type="text/javascript" src="index.js">
</script>
</script>
</head>
<body>
Enter the first number: <input type="text" id="txt1" /><br /> Enter the seccond number: <input type="text" id="txt2" /><br />
<input type="button" onclick="call()" value="Add" />
</body>
</html>
下面是 index.js 文件：
function call() {
var q = parseInt(document.getElementById("txt1").value);
var w = parseInt(document.getElementById("txt2").value);
var result = q + w;
if (isNaN(q) || isNaN(w)) {
alert("please enter a number");
} else
{
var result = q + w;
alert("The sum is " + result);
}
}
