我导入腾讯im小程序库发现与vant weapp冲突请问怎么解决？

您好：我使用mpvue来开发，使用vant-weapp，在我导入import COS from ‘cos-js-sdk-v5’ 时编译提示

jsEnginScriptError

Component is not found in path “vant-weapp/dist/tag/index” (using by “pages/index”);onAppRoute

Error: Component is not found in path “vant-weapp/dist/tag/index” (using by “pages/index”)

注释掉正常编译，请问要怎么解决？
