It seems like you may be trying to import vue-i18n in your project. vue-i18n is a plugin for Vue.js that makes it easy to internationalize your app.

First, you would need to install the library in your project. You can do this by running:

npm install vue-i18n  

Then you can import it into your project. Here's a basic example of how to set it up:

import Vue from 'vue';  
import VueI18n from 'vue-i18n';  
Vue.use(VueI18n);  
const messages = {  
  en: {  
    message: {  
      hello: 'Hello world',  
    },  
  },  
  ja: {  
    message: {  
      hello: 'こんにちは、世界',  
    },  
  }  
};  
const i18n = new VueI18n({  
  locale: 'en', // set locale  
  messages, // set locale messages  
});  
new Vue({  
  i18n,  
  render: h => h(App),  
}).$mount('#app');  

In this example, two locales are defined: English (en) and Japanese (ja). You can switch the current locale by changing the locale property of the VueI18n instance (i18n.locale = 'ja').

In your components, you can use the $t method to translate text:

<p>{{ $t('message.hello') }}</p>  

This will display "Hello world" or "こんにちは、世界" depending on the currently active locale.
