1.npm安装pinia 2.main.js引入pinia import{creatPinia}from“pinia” app.use{creatPinia()} 3.stores文件夹里面，某个模块.js import{ref，computed}from vue import{defineStore}from ‘pinia’ export const 某变量=defineStore（‘count（某值）’，（）=>{ const count =ref(0) const shuangbeicount =conputed({}=>count.value*2) function 方法名increment（）{ count.valie++ } return {count,shaungbeicount,increment} }） 4.在要使用的vue界面引入 import {usecountstore} from ‘store/sount’ const countstore=usecountstore（）
本值=countstore.count 计算后的二倍值=countstore.shuangbeicount 点击方法@click=“countstore.increment（）”
