'不提供名为'createRouter'的导出' vue 3、vite 和 vue-router

Question

我刚开始在 vue 中使用 vite。当我尝试使用 vue-router 时，出现错误：

SyntaxError: The requested module '/node_modules/.vite/vue-router/dist/vue-router.esm.js?v=4830dca4' does not provide an export named 'createRouter

我的路由器/index.js 看起来像这样：

import {
 createWebHistory,
 createRouter
} from "vue-router";

import Services from "../views/Services.vue";
import Costumers from "../views/Costumers.vue";

const history = createWebHistory();
const routes = [
  {
    path: "/",
    component: Services
  },
  {
    path: "/costumers",
    component: Costumers
  },
];
const router = createRouter({
  history,
  routes
});
export default router;

我的 main.js 看起来像这样：

import { createApp } from 'vue'
import App from './App.vue'
import './index.css'
import router from './router'

createApp(App).use(router).mount('#app')

我的 package.json 看起来像这样：

{
 "name": "frontend",
 "version": "0.0.0",
 "scripts": {
 "dev": "vite",
 "build": "vite build"
},
 "dependencies": {
 "vue": "^3.0.5",
 "vue-router": "^3.4.9"
},
 "devDependencies": {
 "@vitejs/plugin-vue": "^1.0.4",
 "@vue/compiler-sfc": "^3.0.5",
 "autoprefixer": "^10.2.3",
 "postcss": "^8.2.4",
 "tailwindcss": "^2.0.2",
 "vite": "^2.0.0-beta.12"
 }
}

有人知道如何导出路由吗？

Answer 1

如果你检查文件内部'/node_modules/.vite/vue-router/dist/vue-router.esm.js?v=4830dca4'

没有export default语法。仅命名export {}

因此，请使用命名导入来代替导入默认值。

// don't
import VueRouter from 'vue-router'

// do
import { createRouter, createWebHashHistory } from 'vue-router'

您应该卸载当前的 vue-router 模块并通过运行以下命令重新安装与 Vue 3 兼容的最新（版本 4）模块：

npm uninstall vue-router

然后

npm install vue-router@next -S
