如何修复Nodejs Electron软件包错误？

我正在使用electron boilerplate library库并正在使用纱包管理器。

yarn dev命令运行正常。但是，当我尝试通过yarn包制作一个包时，它不会打包，也不会放文件。显示类似的内容：

yarn run v1.17.3
$ yarn build && electron-builder build --publish never
$ concurrently "yarn build-main" "yarn build-renderer"
$ cross-env NODE_ENV=production webpack --config ./configs/webpack.config.main.prod.babel.js --colors
$ cross-env NODE_ENV=production webpack --config ./configs/webpack.config.renderer.prod.babel.js --colors

我不知道为什么会这样。 1周前才打包，我做错了什么？

您解决了吗，您可以提供任何来源吗？
