electron-vue第三方依赖包(带有额外的win软件exe)，打包前生效，打包后不生效
引用pdf-to-printer的npm包，实现打印pdf功能

npm对应问题链接

步骤

1. vue脚手架创建项目
2. 增加`vue-cli-plugin-electron-builder`,组合成electron-vue项目
3. 引入第三方依赖包`pdf-to-printer`（包含一个SumatraPDF-3.4.6-32.exe用于打印pdf）
4. 本地运行`npm run electron:serve`,正常打印
5. `electron:build`打包后,运行打包的程序，测试打印，打印不生效，无报错信息

x.vue（渲染进程）

import { ipcRenderer } from "electron";
ipcRenderer.send("print");
