在vue项目中安装vue-socket.io后在main中引入项目启动报错

import VueSocketio from 'vue-socket.io'
Vue.use(VueSocketio, 'http://socketserver.com:1923'); 

我看文档里是这么用的

import Vue from 'vue'
import store from './store'
import App from './App.vue'
import VueSocketIO from 'vue-socket.io'
import SocketIO from "socket.io-client"

Vue.use(new VueSocketIO({
    debug: true,
    connection: 'http://metinseylan.com:1992',
    vuex: {
        store,
        actionPrefix: 'SOCKET_',
        mutationPrefix: 'SOCKET_'
    },
    options: { path: "/my-app/" } //Optional options
}))

new Vue({
    router,
    store,
    render: h => h(App)
}).$mount('#app')
