Uncaught :请求的模块‘/node_ does /..vite/vue.js?v=535663ae’不提供名为“默认”的导出。

Question

我正在使用一个名为夹持带的js框架(用于区块链)。当我试图使用vue路由器时，我得到了这个错误。

import Vue from "vue"; //Error **does not provide an export named 'default'**
import VueRouter from "vue-router";
import Home from "../views/Home.vue";

Vue.use(VueRouter);

const routes = [
  {
    path: "/",
    name: "Home",
    component: Home,
  },
  {
    path: "/about",
    name: "About",
    // route level code-splitting
    // this generates a separate chunk (about.[hash].js) for this route
    // which is lazy-loaded when the route is visited.
    component: () =>
      import(/* webpackChunkName: "about" */ "../views/About.vue"),
  },
];

 const router = new VueRouter({
  routes,
});
export default router;

当我的vue.d.ts文件看起来像这样

import { CompilerOptions } from '@vue/compiler-dom';
import { RenderFunction } from '@vue/runtime-dom';

export declare function compile(template: string | HTMLElement, options?: CompilerOptions): RenderFunction;

export * from "@vue/runtime-dom";

export { }

router.d.ts文件如下所示

我认为你在使用Vue 3。您应该检查您的vue-router版本。如果您现在只运行npm i vue-router，版本应该是"^3.5.3“。尝试使用npm i vue-router@next安装更新版本。

然后像这样导出路由器：

import {createRouter, createWebHistory}  from 'vue-router'

const routes = [
    {
        path:'/',
        name:"Home",
        component:()=>import('./pages/Home.vue')
    }
    ,
    {
        path:'/about',
        name:"About",
        component:()=>import('./pages/About.vue')
    }
]

const router = createRouter({
    history:createWebHistory(),
    routes
})

export default router

从技术上讲，你没有问问题，我会尽力解释错误的。您的错误说明您试图做什么，从不存在的模块'vue‘导入默认导出。

// some ts file
import Vue from "vue";

// the module
export default {}

如果应该有一个名为“Vue”的名导出，您应该按以下方式编写它：import { Vue } from 'vue'
