electron-builder打包时github包下载失败【解决办法】

各位朋友们，在使用electron开发时，选择了electron-builder作为编译打包工具时，是否经常遇到无法从github上下载依赖包问题，如下报错：

Get " github /electron/electron/releases/download/v6.1.12/electron-v6.1.12-win32-ia32.zip": dial tcp 20.205.243.166:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. github /develar/app-builder/pkg/download.(*Downloader).follow.func1 /Volumes/data/Documents/app-builder/pkg/download/downloader.go:206 github /develar/app-builder/pkg/download.(*Downloader).follow /Volumes/data/Documents/app-builder/pkg/download/downloader.go:234 github /develar/app-builder/pkg/download.(*Downloader).DownloadNoRetry /Volumes/data/Documents/app-builder/pkg/download/downloader.go:128 github /develar/app-builder/pkg/download.(*Downloader).Download /Volumes/data/Documents/app-builder/pkg/download/downloader.go:112 github /develar/app-builder/pkg/electron.(*ElectronDownloader).doDownload /Volumes/data/Documents/app-builder/pkg/electron/electronDownloader.go:192 github /develar/app-builder/pkg/electron.(*ElectronDownloader).Download /Volumes/data/Documents/app-builder/pkg/electron/electronDownloader.go:177 github /develar/app-builder/pkg/electron.downloadElectron.func1.1 /Volumes/data/Documents/app-builder/pkg/electron/electronDownloader.go:73 github /develar/app-builder/pkg/util.MapAsyncConcurrency.func2 /Volumes/data/Documents/app-builder/pkg/util/async.go:68

原因就是github被墙，无法访问导致。

那么，解决办法也很简单：

1、找到可替代github的镜像，从这里手动下载对应zip包，推荐一个： github.xzc888.top

把github域名替换为上述镜像域名，如图：

github /electron/electron/releases/download/v6.1.12/electron-v6.1.12-win32-ia32.zip 替换为： github.xzc888.top/electron/electron/releases/download/v6.1.12/electron-v6.1.12-win32-ia32.zip

然后访问，完成下载，如图：

2、下载到zip包后，放到对应目录下：C:\Users\{username}\AppData\Local\electron\Cache

把下载后的zip包拷贝到目上述目录下，如图：

3、再次运行打包即可

备注：一点一滴，皆是成果！
