Laravel9 与 Vue2

Question

我使用命令

laravel new blog

writer require laravel/ui

php artisan ui vue

npm install vue-router

npm install

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

安装了 Laravel 和 Vuejs它给出了当我执行这个命令时出现错误 ‍npm 运行手表

Answer 1

您安装了与 vue2 不兼容的依赖项。

尝试更改 vue-router 和 vuex 版本。

尝试安装以下版本 -

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