pages.json 国际化不生效

按照官网的demo配置的国际化，vue页面中正常，但是pages.json中没有生效，直接就是字符串显示
如图

local文件夹路径

pages.json中 tabbar的配置

main.ts文件

import { createSSRApp } from "vue";  
import { createI18n } from "vue-i18n";  
import App from "./App.vue";  
import { en, zh } from '/locale';  
import uviewPlus from 'uview-plus';  

export type LocaleMessages_type = keyof typeof messages;  

const messages = {  
  en,  
  'zh-Hans': zh  
};  

const i18n = createI18n({  
  locale: uni.getLocale(), // 获取已经设置的语言  
  messages, // 翻译字典  
  legacy: false, // VUE3 中使用组合式API，必须设置为 false,  
  globalInjection: true // 全局注入 $t 函数  
});  

export function createApp() {  
  const app = createSSRApp(App);  
  app.use(i18n);  
  app.use(uviewPlus as any);  

  // 配置uview-plus内部的各项内置配置  
  uni.$u.setConfig({  
    // 修改$u.config对象的属性  
    config: {  
      // 修改默认单位为rpx，相当于执行 uni.$u.config.unit = 'rpx'  
      unit: 'rpx'  
    },  
    // 修改$u.props对象的属性  
    props: {  
      // 修改radio组件的size参数的默认值，相当于执行 uni.$u.props.radio.size = 30  
      radio: {  
        size: 15  
      }  
      // 其他组件属性配置  
      // ......  
    }  
  });  

  return { app };  
}
