Vue-awesome-swiper css翻譯報錯

使用swiper直接從官網(wǎng)占的代碼，但是總是報錯，將css注釋掉之后就不報錯
報錯信息如下

代碼如下主文件代碼

請輸入代碼import Vue from "vue";
import App from "./container/App.vue";
import Vuex from "vuex";
import VueRouter from "vue-router";
import store from "./store.js";
import routes from "./routes.js";
import VueAwesomeSwiper from 'vue-awesome-swiper';
import 'swiper/dist/css/swiper.css';
Vue.use(VueAwesomeSwiper);
Vue.use(Vuex);
Vue.use(VueRouter);
const router = new VueRouter({routes})
new Vue({
    "el":"#app",
    "data":{},
    //注冊組件
    "components":{
        App
},
    render(h){
    return h(App)
    },
   store : new Vuex.Store(store),
   router
})
