javascript - 无法修复 Electron React 样板包错误

Question

我正在使用 electron-react-boilerplate创建桌面应用程序。我正在使用 yarn 包管理器。

我在 4 个月前编译了这个应用程序。但是现在无法编译。

当我写 yarn package命令，它显示此错误:

yarn run v1.21.1
$ 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

这是 yarn package命令脚本:

"package": "yarn build && electron-builder build --publish never",

所以你使用的是旧版本的 electron-builder使用 yarn add electron-builder@latest 更新到最新版本并尝试yarn package再次
