cnpm install vue-i18n --save-dev 

import Vue from 'vue' 
import router from './router' 
import VueI18n from 'vue-i18n' 
Vue.use(VueI18n) 
const i18n = new VueI18n({ 
 locale: 'zh', // 语言标识 
 messages: { 
  'zh': require('./assets/lang/zh'),

{{$t('menu.home')}}
 

console.log(this.$t('content.main')); 

tabEn: function () {
