项目中要使用图片验证 码，使用了npm上的轻量级ccap模块，开发环境上安装正常，到了发布环境上，怎么也装不上。系统输出如下： ` [root@localhost QAVA]# npm install -g ccap

ccap@0.6.0 preinstall /usr/local/n/versions/node/0.12.2/lib/node_modules/ccap node make.js

I’m glad you to select ccap, enjoy it!

ccap is a cross plat form and portable nodejs simple captcha module, simple api and lightweight.

starting compile ccap! good luck! \

ccap@0.6.0 install /usr/local/n/versions/node/0.12.2/lib/node_modules/ccap node-gyp rebuild

目前与开发机唯一不同在于开发机是32位系统，发布机器是64位系统， 求解。
