vue代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>vue-HTML</title>
</head>
<body>
<!-- html结构 -->
<div id="app">
<p v-html="content"></p>
<p v-text="content"></p>
</div>
<script type="text/javascript" src="https://cdn.jsdeliver.net/npm/vue/dist/vue.js"></script>
<script>
import Vue from "vue";
let app = new Vue(
{
el: "#app",
data: {
// content: "mac"
content: "<a href='https://www.itheima.com>黑马程序员</a>'"
}
}
);
</script>
</body>
</html>
问题，如图片所示，运行之后无任何显示，大致问题是什么导致？：
