【问题描述】：

我是Vue.js 的新手，第一次与vue-router 打交道。刚刚创建了一些文件，由于某种原因我看不到模板。编译成功但在浏览器中出现以下错误：Failed to resolve component: router-view

main.js

import { createApp } from 'vue';
import VueRouter from 'vue-router';
import { store } from './store';
import App from './App.vue';
import AuthHandler from './components/AuthHandler';

const router = new VueRouter({
    mode: 'history',
    routes: [
        { path: '/oauth2/callback', component: AuthHandler }
    ]
});

const app = createApp(App)
app.use(router)
app.use(store)
app.mount('#app')

App.vue

<template>
  <div>
    <AppHeader></AppHeader>
    <router-view></router-view>
  </div>
</template>

<script>
import AppHeader from "./components/AppHeader";
export default {
  name: "App",
  components: {
    AppHeader
  }
};
</script>

组件/AuthHandler.vue

<template>
  <div>
    ... Please wait
  </div>
</template>

<script>
export default {
  name: "AuthHandler"
};
</script>

这是 package.json

【解决方案1】：

我通过以下方式解决了问题。我相信问题会在 vue/vue-router 版本上出现。我希望这是正确的方法:-)

main.js

import { createApp } from 'vue';
import App from './App.vue';
// import VueRouter from './vue-router';
import { createWebHistory, createRouter } from "vue-router";
import { store } from './store';
import AuthHandler from './components/AuthHandler';

const router = createRouter({
    history: createWebHistory(),
    routes: [
        { path: '/about', component: AuthHandler }
    ]
});

const app = createApp(App)
app.use(router)
app.use(store)
app.mount('#app')
