vue.js - vuex：mapActions中的错误未知操作类型

Question

在我的组件中，我试图从模块执行vuex操作，但是我收到错误，即使定义了这个操作：

的console.log

DELETE USER:  14
ListUsers.vue:131
[vuex] unknown action type: deleteUser

UPDATE插入了模板

这是我的ListUsers.vue中的完整模板

在每个表格行中，我有一个垃圾图标，用于触发模态面板（ref =“delUserModal”）以确认删除操作

  <b-btn class="btn" variant="danger" block 
    @click="onAction('delete-user', props.row)">Yes, Delete It
  </b-btn>

ListUsers.vue

<template>
  <div id="users">
    <v-server-table name='users' url="users" ref='userTable' :columns="columns" :options="options">
      <template slot="afterBody">

当将vuex与vue-tables-2一起使用时，会从表组件中使用名称prop注册一个模块

useVuex is a boolean indicating whether to use vuex for state management, 
or manage state on the component itself. If you set it to true you must 
add a name prop to your table, which will be used to to register a module 
on your store. Use vue-devtools to look under the hood and see the current state.

我正确地将自己的操作添加到此模块中，（deleteUser：（store，id）就在那里）...但我不幸地将这个'users'模块声明为namespaced = true ...将其更改为false或将操作调用为namespaced解决了这个问题......
