## Vue报错“ Uncaught TypeError: Cannot read property ‘use‘ of undefined” ##

### 错误全程 ###

Cannot read properties of undefined (reading ‘use’) TypeError: Cannot read properties of undefined (reading ‘use’) at eval (webpack-internal:///./src/store/index.js:6:45) at ./src/store/index.js (http://localhost:8080/js/app.js:96:1) at \_

### 错误分析 ###

这个错误说的是use这个方法没有定义

回到前端代码，发现这里使用了Vue.use，但是上面错误提示里面显示里面没有，原因是因为下面这个写法是Vue2的写法，vue3的话需要修改一下。

修改成下面这个格式

import {
         createStore } from 'vuex'
    
    export default createStore({
        
        state: {
        
            
        }
    })
