1. 打开插件文件夹 

   文件夹名是 "作者名.vscode-插件名-版本号"组成的.

   C:\Users\Administrator\.vscode\extensions\sdras.vue-vscode-snippets-3.1.1\snippets

2. 打开vue.json

   "prefix": "vbase" 就是代码块的关键词,输入vbase就会提示代码块        

        上面的TT就是修改后的效果

3.增加自己代码填

"Vue Single File Component": {
    "prefix": "vbt",
    "body": [
      "<template>",
      "\t<div>",
      "",
      "\t</div>",
      "</template>",
      "",
      "<script>",
      "\texport default {",
      "\t\t${0}",
      "\t}",
      "</script>",
      "",
      "<style lang=\"scss\" scoped>",
      "",
      "</style>"
    ],
    "description": "Base for VueTT File with SCSS"
  },

保存后重启vscode
