Cannot read property 'matched' of undefined"

错误代码 D:workspacexxxsrcmain.js

const routes = new VueRouter({
  routes: [
    {
      path: '/apple',
      component: Apple
    },
    {
      path: '/banana',
      component: Banana
    }
  ]
})
/* eslint-disable no-new */
new Vue({
  el: '#app',
  routes,
  template: '<App/>',
  components: { App }
})

　　

正确代码1

const router = new VueRouter({
  routes: [
    {
      path: '/apple',
      component: Apple
    },
    {
      path: '/banana',
      component: Banana
    }
  ]
})
/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  template: '<App/>',
  components: { App }
})

　　

正确代码2

const routes = new VueRouter({
  routes: [
    {
      path: '/apple',
      component: Apple
    },
    {
      path: '/banana',
      component: Banana
    }
  ]
})
/* eslint-disable no-new */
new Vue({
  el: '#app',
  router: routes,
  template: '<App/>',
  components: { App }
})

　　

错误分析： router才是合法参数，缩写的时候要注意。

另外 path: './apple',  应该是path: '/apple'

const routes = new VRouter({
  routes: [
    {
      path: './apple',
      component: Apple
    },
    {
      path: './banana',
      component: Banana
    }
  ]
})
