1.在 vscode 中找到如图设置->代码片段->vue.json

2.配置默认值

{
	"vue3": {
		"prefix": "vue3",
		"body": [
			"<template>",
			"  <div></div>",
			"</template>",
			"",
			"<script setup lang='ts'>",
			"import {ref,reactive} from 'vue'",
			"",
			"</script>",
			"<style scoped>",
			"",
			"</style>"
		],
		"description": "vue3"
	},
	"vue2": {
		"prefix": "vue2",
		"body": [
			"<template>",
			"  <div></div>",
			"</template>",
			"",
			"<script>",
			"",
			"</script>",
			"<style scoped>",
			"",
			"</style>"
		],
		"description": "vue2"
	}
}

3. 在vue 文件中输入 vue3 就会自然而然出现该提示
