Vue 项目提示:`(Emitted value instead of an instance of Error) the “scope“ attribute for scoped slots

Vue 完整警告信息:

`(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. The n
ot-scope" attribute can also be used on plain elements in addition to <template> to denote scoped slots.`

造成原因：

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

办法解决:

检查下你的列表组件里，slot 里的 <template> 上面有个 scope 属性，你改成 slot-scope.

                    <el-table-column label="操作"><template slot="scope"><el-button type="primary" size="mini" @click="toEdit(scope.$index, scope.row)">编辑</el-button><el-button type="primary" size="mini" @click="deleteAdmin(scope.$index, scope.row)">删除</el-button></template></el-table-column>

改成

                        <el-table-column label="操作"><template slot-scope="scope"><el-button type="primary" size="mini" @click="toEdit(scope.$index, scope.row)">编辑</el-button><el-button type="primary" size="mini" @click="deleteAdmin(scope.$index, scope.row)">删除</el-button></template></el-table-column>
