ubuntu node 安装 canvas不成功

Question

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! canvas@0.10.2 preinstall: node-waf configure build
npm ERR! Exit status 127
npm ERR!
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.
npm ERR! Tell the author that this fails on your system:
npm ERR! node-waf configure build
npm ERR! You can get their info via:
npm ERR! npm owner ls canvas
npm ERR! There is likely additional logging output above.

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!
