vue 热更新 record.Ctor.super.extend(options) 报错

{
 "vue": "^2.6.12",
 "vue-hot-reload-api"：“@^2.3.0“
}

node_modules\vue-hot-reload-api\dist\index.js

exports.reload = tryWrap(function (id, options) {
      var record = map[id]
  
      //这里报错 经调试，super是undefined
      //var newCtor = record.Ctor.super.extend(options)
      
      // 改成这样不报错
      var newCtor = record.Ctor.extend(options)
})
