使用electron-builder打包时下载electron失败解决方案

Posted 2021-03-07 xiaoniuzai

electron-builder 在打包时会检测cache中是否有electron 包，如果没有的话会从github上拉去，在国内网络环境中拉取的过程大概率会失败，所以你可以自己去下载一个包放到cache目录里

各个平台的目录地址

Linux: $XDG_CACHE_HOME or ~/.cache/electron/
MacOS: ~/Library/Caches/electron/
Windows: %LOCALAPPDATA%/electron/Cache or ~/AppData/Local/electron/Cache/

参考：https://github.com/electron/get#how-it-works

例如在macos平台打包electron应用，执行 electron-builder --mac --x64

?  clipboard git:(master) ? npm run dist

> clipboard@1.0.0 dist /Users/xx/workspace/electron/clipboard
> electron-builder --mac --x64

  ? electron-builder  version=22.3.2 os=18.7.0
  ? loaded configuration  file=package.json ("build" field)
  ? writing effective config  file=dist/builder-effective-config.yaml
  ? packaging       platform=darwin arch=x64 electron=8.0.0 appOutDir=dist/mac
  ? downloading     url=https://github.com/electron/electron/releases/download/v8.0.0/electron-v8.0.0-darwin-x64.zip size=66 MB parts=8

可以单独下载这个包 https://github.com/electron/electron/releases/download/v8.0.0/electron-v8.0.0-darwin-x64.zip， 放到~/Library/Caches/electron/ 目录下

然后可以打包完成
