First I used Hbuilder to run through the first Vue project
Steps:
1. Create a new Vue project
2. Vue project . After creation, right-click on the newly created project to create an index.html file
3. On the Vue official website, download a Vue.js file and place it in Create a Vue project, under the src package, easy to use 
4. Write the first Vue code
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Hello vue</title>
<script src="./src/vue.js" type="text/javascript" charset="UTF-8"></script>
<!-- 引入vue.js 要不然无法运行-->
</head>
<body>
<div id="demo">
{
{
message}}
</div>
<script type="text/javascript">
var demo=new Vue(
{
el:'#demo',
data:{
message:'hello vue!!!'
}
}
);
</script>
</body>
</html>
Save, then run.
