在static/lang下新建文件：

index.js、en.js、zh.js...

// en.jsmodule.exports = {  route: {    title: 'chengdu',  }    }// zh.jsmodule.exports = {  route: {    title: '成都',  }    }// index.jsimport path from 'path'import fs from 'fs'let files = fs.readdirSync(path.join('./', 'static', 'lang'))let langPack = {}for (let file of files) {  if (file !== 'index.js') {    langPack[file.replace(/.js/, '')] = require(`./${file}`)  }}export deafult langPack

然后在src/store/plugins下的i18n.js中使用插件方式引入vue-i18n

import * as types from '../types'import VueI18n from 'vue-i18n'import langPack from '@/../static/lang'import Vue from 'vue'Vue.use(VueI18n)export const i18n = new VueI18n({  locale: 'zh',  messages: langPack,})function i18nPlugin (store) {  store.subscribe((mutation, state) => {    if (mutation.type === types.SET_LANGUAGE) {      i18n.locale = mutation.payload.toString()    }  })}export default i18nPlugin

记得要在store/index.js中引入插件以及使用mutation的方式改变state。
