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 > vue-admin-template@1.0.0 dev /Users/crifan/dev/xxx > node build/dev-server.js > Starting dev server… WARNING Compiled with 6 warnings warning in ./src/views/table/index.vue (Emitted value instead of an instance of Error) the “scope” attribute for scoped slots have been deprecated and replaced by “slot-scope” since 2.5.

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
“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。
