require.js, when you output window in the console, you can see that there are Vue instances, but the output window.Vue shows undifind
. I mainly want to call vux"s loading plug-in through the vue instance, but I can"t get this instance to ask for help

import axios from "axios"

import  { LoadingPlugin  } from "vux"
import Vue from "vue"
Vue.use(LoadingPlugin)

console.logwindow
console.log(window.Vue)

 function fetch(config) {
  return new Promise((resolve, reject) => {
    const instance = axios.create({
      transformRequest: [function (data) {
       return data
      }]
    }); 
    instance.interceptors.request.use(config => {
      config.headers["Content-Type"]= "application/x-www-form-urlencoded";
      return config
    }, error => {
      Promise.reject(error)
    })
    instance(config).then(res => {
      //  console.log(res);
      resolve(res);
      //
    }).catch(err => {
      console.log(err);
      reject(err);
    })
  });
}

 function myaxios(url,type,data,msgtype) {
      return fetch({
        url: url,
        method: type,
        data: data,
        headers:  {
        }
      })
  }
    export default myaxios

in main.js

import  myaxios  from "./utils/require"
 Vue.prototype.$axios = myaxios
