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 "https://github.com/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.

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：https://github.xzc888.top
把github域名替换为上述镜像域名，如图：
https://github.com/electron/electron/releases/download/v6.1.12/electron-v6.1.12-win32-ia32.zip
替换为：
https://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！
