在原生小程序 vue，mpvue中关于vant组件库的引入的那些坑_van-transition 不生效

原生小程序中引入vant框架的方法

先在项目文件下 cmd进入终端
npm init -y 生成一个package-lock.json文件 进行初始化项目配置
引入vant 包 ：npm install vant --save
或者npm i @vant/weapp -S --production

然后在详情中勾选下列选项
这里es6转es5可勾可不勾
一定要勾选使用npm模块

然后在开发者工具中 工具–>构建npm
接下来就可以看到一个 miniprogram_npm的文件夹

在app.json中或者index.json中添加 配置

 "usingComponents": {
   
    "van-button": "@vant/weapp/button/index",
     "van-slider":"@vant/weapp/slider/index",
     "van-tree-select":"@vant/weapp/tree-select/index",
