更新-continew3.6修复了这个问题，前端doc等问题不会报错

Failed to resolve entry for package "@vue-office/pdf". The package may have incorrect main/module/exports specified in its package.json.

修改src/components/FilePreview/index.vue文件

注释掉原来的

// import VueOfficePdf from '@vue-office/pdf'

import VueOfficePdf from '@vue-office/pdf/lib/v3/vue-office-pdf.mjs'

import VueOfficeDocx from '@vue-office/docx/lib/v3/vue-office-docx.mjs'

// import VueOfficeDocx from '@vue-office/docx'

import '@vue-office/docx/lib/v3/index.css'

// import '@vue-office/docx/lib/index.css'

import VueOfficeExcel from '@vue-office/excel/lib/v3/vue-office-excel.mjs'

import '@vue-office/excel/lib/v3/index.css'

import { Message } from '@arco-design/web-vue'

页面正常
