import Vue from 'vue'; //配置路由 import VueRouter from 'vue-router' Vue.use(VueRouter);

这段代码是在Vue.js中使用Vue Router进行路由配置的代码。首先，通过`import`语句引入Vue和Vue Router库。然后，通过`Vue.use()`方法将Vue Router注册为Vue.js的插件。最后，可以在Vue实例中使用Vue Router提供的组件和方法进行路由配置和管理。

这个报错是因为在使用Vue Router时，导入的Vue Router版本与当前项目中的Vue版本不匹配导致的。具体来说，Vue Router中使用了Vue 3的语法而当前项目中使用的是Vue 2，所以会出现一些语法上的错误。解决方法是将Vue Router更新到与当前项目中使用的Vue版本相匹配的版本。

import Vue from 'vue' import App from './App.vue' import dateUtil from './libs/dateUtil' import router from './router' import store from './store' import ElementUI from 'element-ui' import http from './libs/http' import Apis from './libs/api' import 'reset.css/reset.css' import 'bpmn-js/dist/assets/diagram-js.css' import 'bpmn-js/dist/assets/bpmn-font/css/bpmn.css' import 'bpmn-js/dist/assets/bpmn-font/css/bpmn-codes.css' import 'bpmn-js/dist/assets/bpmn-font/css/bpmn-embedded.css' import './components/bpmn/assets/css/vue-bmpn.css' import 'element-ui/lib/theme-chalk/index.css' import './assets/css/element-ui.css' import './assets/css/iconfont.css' Vue.config.productionTip = true Vue.use(http).use(ElementUI).use(dateUtil) Vue.prototype.Apis = Apis new Vue({ render: h => h(App), router, store }).$mount('#app')

这段代码是一个 Vue.js 项目的入口文件，主要作用是引入各种依赖和配置，并启动应用。其中，import 语句用于引入各种依赖，包括 Vue.js 框架本身、第三方组件库 ElementUI、自定义的工具类 dateUtil、http 封装库和接口定义文件 Apis。接着，设置了一些全局的配置，包括 Vue 的生产模式提示、注册所需的插件和挂载接口定义文件。最后，创建了一个 Vue 实例，并将其挂载到指定的 DOM 元素上。在这个实例中，使用了 App.vue 组件作为根组件，并传入了路由和 Vuex 状态管理对象作为参数。整个项目的运行逻辑都是由这个入口文件启动的。
