如何将vue路由器与vue 2配合使用。x版本

Question

从“Vue”导入Vue从“Vuex”导入Vuex从“Vue路由器”导入VueRouter从“es6promise/自动”

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import App from './App.vue'

//import About from "./components/About.vue"

Vue.config.productionTip = false
Vue.use(ElementUI);
Vue.use(Vuex)
Vue.use(VueRouter)

const store = new Vuex.Store({ ... })

const routes = [
  { path: '/about', component: { template: '<div>foo</div>' } },
]

const router = VueRouter({
  routes, // short for `routes: routes`
})

new Vue({
  render: h => h(App),
  router,
  store,
}).$mount('#app')

我尝试使用路由器，但它给出以下错误：

Uncaught TypeError: this is undefined
    VueRouter vue-router.esm.js:2699
    <anonymous> main.js:84
    js app.js:1351
    __webpack_require__ app.js:849
    fn app.js:151
    1 app.js:1364
    __webpack_require__ app.js:849
    checkDeferredModules app.js:46
    <anonymous> app.js:925
    <anonymous> app.js:928

    VueRouter vue-router.esm.js:2699
    <anonim> main.js:84
    js app.js:1351

    __webpack_require__ app.js:849
    checkDeferredModules app.js:46
    <anonim> app.js:925

我创建了我的项目vue cli，然后用npm-I安装了vue路由器，为什么不这样做，或者应该使用vue add routercli命令添加？

以下是我的版本：

    "vue": "^2.6.12",
    "vue-router": "^3.2.0",
    "vuex": "^3.6.2"
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-plugin-router": "^4.5.11",
    "@vue/cli-service": "~4.5.0",
    "babel-eslint": "^10.1.0",
    "babel-plugin-component": "^1.1.1",
    "eslint": "^6.7.2",
    "eslint-plugin-vue": "^6.2.2",
    "vue-template-compiler": "^2.6.11"

该错误不是VueRouter导入中的错误，而是VueRouter使用中的错误。

函数是获取路由器实例的构造函数。在你的代码中，你必须这样做来解决你的问题：

const router = new VueRouter({
  routes, // short for `routes: routes`
})
