After checking bit by bit , Found other references request.js There is no problem with the interface files , Only login Interface file reference error .

All kinds of checks What's the reason ？ Unsolved You know, great Xia, you can help solve your doubts , thank you

But if you just have to use pop-up components You can use the following methods

//1. First introduce `vue`
import Vue from 'vue'

//2. establish vue Example 
let v = new Vue()

//3. adopt vue Instance call component 
v.$message.success(' Content ')

It's finally done ！ Goodbye for a long time
