clientAppEnhance.js

import './fit.js'
import { defineClientAppEnhance } from '@vuepress/client'
import d from './components/d.vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import index from '../../package/index'
import '../../package/style.scss'
import mycode from './components/mgcode.vue'


export default defineClientAppEnhance(({ app, router, siteData }) => {
  app.component('d', d)
  app.component('mycode', mycode)
  app.use(ElementPlus)
  app.use(index)
  app.use(router)
})

fit.js

if (typeof global === 'undefined') {
  global = this
}

I don't know that the problem may be in webpack or the clientAppEnhance.js config.js
