异常文本:
TypeError: Cannot use 'in' operator to search for '__v_isRef' in undefined

[Vue warn]: Error in nextTick: "TypeError: Cannot use 'in' operator to search for '__v_isRef' in undefined"

Property or method "__v_isRef" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.

使用版本:
"element-ui": "2.15.5",
"vue": "^2.6.11",
"vue-router": "^3.5.2"

此异常导致问题:
element-ui组件在页面上可以显示但不可用,点击无效,而且一些小的ico都显示为方框
