npm ERR! Failed at the canvas@0.10.2 preinstall script.
npm ERR! This is most likely a problem with the canvas package
npm ERR! not with npm itself.

已经好几天，在线等，希望有懂的人告诉我
解决方案
npm install canvas 各种依赖各种错误 转投npm install ccap 来生成验证码
他的依赖很多最好按照官方wiki提供的文档来安装.
wiki文档地址: https://github.com/LearnBoost/node-canvas/wiki
wiki 提供的安装向导包括2部分红框内的为不同操作系统需要安装的依赖. 红框下面是云环境需要安装的依赖.
其实我在博客中只是想生成一个验证码涉及到的功能很小于是网上查找替换方案就这样发现了ccap 眼前一亮的感觉!
