Error: Application entry file "dist\electron\main.js" in the "D:\gui\demo2\build\win-unpacked\resources\app.asar" does not exist. Seems like a wrong configuration.

从第一句报错：

Error: Application entry file "dist\electron\main.js" in the "D:\gui\demo2\build\win-unpacked\resources\app.asar" does not exist. Seems like a wrong configuration.

出现错误的原因：.electron-vue\build.js文件中，代码中使用了 Multispinner ，但没有在开头引用，并且package.json文件中也没有这个依赖文件。

要解决这个问题首先是先安装

npm install multispinner -D

然后在.electron-vue\build.js文件中引用

const Multispinner = require('multispinner')

再重新进行打包即可。
