错误信息如下：

app.js:669 Uncaught Error: [🍍]: getActivePinia was called with no active Pinia. Did you forget to install pinia?
const pinia = createPinia()
app.use(pinia)

原因：

是因为在setup 之外使用了pinia

解决办法

重新引入pinia

1、在store 文件夹建立一个pinia.js

import { createPinia } from 'pinia'
export const pinia = createPinia()

2、 store 文件夹建立一个index.js 并引入pinia.js

export * from './pinias'
export * from './user'

3、require.js 里使用

import { pinia, userStore } from '@/store'
const store = userStore(pinia)
