vue 2.7 this._watchers is undefined in core.js

Open topmaxz opened this issue 2 years ago • 4 comments

Summary 简述

vue2工程升级到2.7后原v-charts页面会报错，如下图所示

打印this时也发现没有_watchers属性，只有_watcher

Expect 期望结果

希望尽快修复该错误，应该是比较简单的

提供一个不修改源码的思路

在App入口文件, Vue对象实例化之前, 加入

Vue._watchers = Vue.prototype._watchers = []

多个Vue对象同理
