Invalid 'main' field in 'D:\Noot-working\braider\dist_electron\package.json' of 'background.js'.

在运行electron的时候，出现了以下提醒，是因为build后的dist文件有index.js和package.json,冲突出现在这个文件夹，需要我们把文件夹名修改成background.js即可。

Invalid 'main' field in 'D:\Noot-working\braider\dist_electron\package.json' of 'background.js'. Please either fix that or report it to the module authorraider\dist_electron\package.json' of 'background.js'. Please either fix that or report it to the module author

(Use `electron --trace-deprecation ...` to show where the warning was created)

解决方法：在vue.config.js中添加以下代码：

electronBuilder: {
      chainWebpackMainProcess: (config) => {
        config.output.filename('background.js');
      },
}

 最后再运行级不报错啦
