npm安装vue路由器

npm安装

app.js

window.Vue = require('vue').default;
import router from "./router/router";
const app = new Vue({
    el: '#app',
    router
});

router/router.js

import VueRouter from 'vue-router'

Vue.use(VueRouter)

const routes = [
    {
        path: '/',
        name: 'Home',
        component: () => import('../components/ExampleComponent.vue')
    }
]

const router = new VueRouter({
    mode: 'history',
    base: process.env.BASE_URL,
    routes
})

export default router

当我执行此命令‍npm运行监视时，会出现一个错误。

Answer 1

您已经为vue2安装了不兼容的依赖项。

尝试更改vue-router和vuex版本。

试着安装以下版本-

"vuex": "^3.6.2",
"vue-router": "^3.5.1",
