报错码

VM292:1 thirdScriptError sdk uncaught third Error module "miniprogram_npm/vant-weapp/mixins/transition" is not defined Error: module "miniprogram_npm/vant-weapp/mixins/transition" is not defined at require (http://127.0.0.1:56368/appservice/__dev__/WAService.js:22:26700) at http://127.0.0.1:56368/appservice/__dev__/WAService.js:22:26448 at http://127.0.0.1:56368/appservice/miniprogram_npm/vant-weapp/popup/index.js:5:19 at require (http://127.0.0.1:56368/appservice/__dev__/WAService.js:22:26841) at <anonymous>:395:7 at HTMLScriptElement.scriptLoaded (http://127.0.0.1:56368/appservice/appservice?t=1557802464868:4544:21) at HTMLScriptElement.script.onload (http://127.0.0.1:56368/appservice/appservice?t=1557802464868:4556:20) 

解决方法：

你只需要把miniprogram_npm/vant-weapp里的组件文件夹都删除，

之后再https://github.com/youzan/vant-weapp下载一份vant， 将dist文件夹（vant-weapp-dev\vant-weapp-dev\dist）中的文件复制到项目的miniprogram_npm/vant-weapp

即下载一份vant，之后替换掉项目中的文件

之后保存解决
