vuejs组件加载失败

Question

使用vue ui和inspect任务来验证webpack.config.js，完成后没有报告错误，但引导时出现应用程序错误。加载失败似乎不是位置，而是文件在预期的位置。

控制台输出

  [vue-router] Failed to resolve async component default: Error: Loading chunk home failed.
  (error: http://localhost:63660/wwwroot/dist/home.js) vue-router.esm.js:17:39

  [vue-router] uncaught error during route navigation: vue-router.esm.js:17:39
  Error: "Loading chunk home failed.

 vue-router.esm.js:1898:9

 Loading failed for the <script> with source 
 “http://localhost:63660/wwwroot/dist/home.js”. localhost:63660:1:1

web.config.js

  const bundleOutputDir = "./wwwroot/dist/";

output配置定义

   output: {
        filename: "[name].js",
        path: path.join(__dirname, bundleOutputDir),
        publicPath: path.join(__dirname, bundleOutputDir),
    },

main.ts

定义的路线

   const routes = [
   {
    path: '/', name: 'home',
    component: () => import(/* webpackChunkName: "home" */ './views/Home.vue'),
   },
   {
    path: '/fetchdata', name: 'fetchdata',
    component: () => import(/* webpackChunkName: "fetchdata" */ './components/fetchdata/fetchdata.vue')},
   {
      path: '/about', name: 'about',
      component: () => import(/* webpackChunkName: "about" */ './views/About.vue'),
   },
  ];

 new Vue({
  router: new VueRouter({ mode: 'history', routes }),
  store,
  render: (h) => h(App),
 }).$mount('#app-root');

App.vue

  <template>
  <div id='app-root' class="container-fluid">
    <div class="row">
        <div class="col-sm-3">
            <menu-component />
        </div>
        <div class="col-sm-9">
            <router-view></router-view>
        </div>
    </div>
   </div>
 </template>

<script lang="ts">
  import Vue from 'vue';
  import { Component } from 'vue-property-decorator';

  @Component({
    components: {
     MenuComponent: require('./components/navmenu/navmenu.vue'),
    },
  })

    export default class AppComponent extends Vue {
    }
  </script>

index.cshtml（应用程序条目）

  @{
     ViewData["Title"] = "Home Page";
  }

  <div id='app-root'>Loading...</div>

  @section scripts {
     <script src="~/dist/main.js" asp-append-version="true"></script>

Answer 1

这是一个愚蠢的错误……与往常一样，错误输出可以清楚地看到答案，但是我被太多的新事物所困扰，无法看到它。 publicPath被设置为静态根目录（wwwroot / dist），因此所提供的URL包括wwwroot。解决方法是仅指定dist/而不是wwwroot/dist //publicPath: path.join(__dirname, bundleOutputDir),

   output: {
        filename: "[name].js",
        path: path.join(__dirname, bundleOutputDir),
        publicPath: "dist/",
        libraryExport: "default",
    },
