折腾:

【已解决】npm WARN element-ui@2.0.1 requires a peer of vue@^2.5.2 but none was installed

期间,vue升级到2.5.2后,npm run dev出现警告:

➜  HeadquarterReport git:(permission-control) ✗ npm run dev

好像是直接把scope改为slot-scope就可以了?

the scope attribute for scoped slots have been deprecated and replaced by slot-scope since 2.5

Vue 2.5 Scope attribute deprecated replaced by slot-scope · Issue #283 · ratiw/vuetable-2

Vue 2.5 release details

“In 2.5, the scope attribute has been deprecated (it still works, but you will get a soft warning). Instead, we now use slot-scope to denote a scoped slot, and it can be used on a normal element/component in addition to <template>:

<comp>

  <div slot-scope=”props”>

    {{ props.msg }}

  </div>

</comp>

Note that this change means that slot-scope is now a reserved attribute and can no longer be used as a component prop.

Vue2.5 scoped slots deprecated – Get Help – Vue Forum

Upgrading to Vue.js 2.5 ← Alligator.io

vue项目报错如下:(Emitted value instead of an instance of Error) – CSDN博客

“scope 属性在2.5以后的版本中已经废弃, 被 slot-scope 替代

slot-scope 不光可以用在 template 元素上,也可以用在其它元素”

所以就是直接换就好。

【总结】

把:

<template scope=”scope”>
    {{scope.$index}}
</template>

改为:

<template slot-scope=”scope”>
    {{scope.$index}}
</template>

即可。
