想尝试下electron开发桌面应用，于是按照官网的流程试了下，发现了个问题。
一、问题
在使用npm install 命令的时候，发现了个error，导致后面demo起不来，报错内容如下：
PS D:\github\electron-quick-start> npm install > electron@2.0.0 postinstall D:\github\electron-quick-start\node_modules\electron > node install.js Downloading SHASUMS256.txt Error: socket hang up D:\github\electron-quick-start\node_modules\electron\install.js:47 throw err ^ Error: socket hang up at createHangUpError (_http_client.js:331:15) at TLSSocket.socketOnEnd (_http_client.js:423:23) at emitNone (events.js:111:20) at TLSSocket.emit (events.js:208:7) at endReadableNT (_stream_readable.js:1056:12) at _combinedTickCallback (internal/process/next_tick.js:138:11) at process._tickCallback (internal/process/next_tick.js:180:9) npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! electron@2.0.0 postinstall: `node install.js` npm ERR!

处理方法：
更换淘宝的镜像
npm install cnpm -g --registry=http://registry.npm.taobao.org
使用cnpm install更新后没有问题。
不管为啥了，先记下，快去玩electron咯。
