用npm安装canvas用的这两句代码sudo apt-get install libcairo2-dev和npm install canvas
出现错误
sh: 1: node-waf: not found

npm ERR! Exit status 127

已经好几天，在线等，希望有懂的人告诉我
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!
