vue中router正确，但没法显示子页面

vue中router正确但子页面没办法出现东西，没有报错。

import Vue from 'vue'
import VueRouter from 'vue-router'
import accoutPage from '../views/accout/wallet/accoutPage.vue'
import a from '../src/views/accout/a.vue'
import b from '../src/views/accout/b.vue'
import c from '../src/views/accout/c.vue'

Vue.use(VueRouter)

const routes = [
  {
    path: '/accoutPage',
    name: 'accoutPage',
    component: accoutPage,
    redirect:
      { name: 'a' },
    children:
      [
        {
          path: '/account/wallet',
          name: '/account/wallet',
          redirect: '/account/wallet/a',
          component: a,
          meta: {
            title: '页面a'
          }
        },
        {
          path: '/account/wallet',
          name: '/account/wallet',
          redirect: '/account/wallet/b',
          component: b,
          meta: {
            title: '页面B'
          }
        },
        {
          path: 'c',
          name: 'c',
          component: c,
          meta: {
            title: '页面c'
          }
        }
      ]
  }
]

const router = new VueRouter({
  routes
})

export default router

检查一下router-view写的地方是否正确

页面a跟b的path重复了

你将a和b路由重定向到 /account/wallet/a 和 /account/wallet/b
这两个路由并没有定义
你需要定义这两个重定向到的路由

{
          path: '/account/wallet/a',
          name: '/account/wallet/a',
          component: a,
          meta: {
            title: '页面a'
          }
        },
{
          path: '/account/wallet/b',
          name: '/account/wallet/b',
          component: b,
          meta: {
            title: '页面b'
          }
        },
