Vue路由器编程导航不起作用

我使用vue-router在组件中进行程序化导航无法正常工作。成功登录后，我要将其重定向到仪表板页面。但是什么也没发生...

相关代码-路由器：

import Vue from 'vue'
import Router from 'vue-router'
import store from '../store'
import Login from '@/components/Login'
import Dashboard from '@/components/Dashboard'

Vue.use(Router)

export default new Router({
  mode: 'history',
  routes: [
    {
      path: '/login',
      name: 'login',
      component: Login,
      beforeEnter: (to, from, next) => {
        if (store.getters.isAuthenticated) {
          // if user is already authenticated,
          // redirect it to the dashboard
          next('/dashboard') // it works
        } else {
          next()
        }
      }
    },
    {
      path: '/dashboard',
      name: 'dashboard',
      component: Dashboard,
      beforeEnter: (to, from, next) => {
        if (store.getters.isAuthenticated) {
          next()
        } else {
          // if user is not authenticated,
          // redirect it to the login
          next('/login') // it works
        }
      }
    }
  ]
})

组件中的方法：

userLogin () {
  this.authorizeUser({
    name: this.user.name,
    pass: this.user.pass
  }).then(result => {
    console.log('redirected to dashboard')
    this.$router.push('dashboard') // this doesn't work
  })
}

那里没有错误，但也没有采取任何措施-我仍然停留在登录页面上。我想念什么？

编辑：

这有效：this。$ router.go（'dashboard'）这是否意味着我使用的是旧版本？
