初学node.js，尝试运行node.js in action的代码出现了无法安装bcrypt module的问题，按照http://henzil.easymorse.com/?p=510 操作后还是有问题，希望能得到解答，十分感谢！

D:\node\nodejsinaction\9\shoutbox>npm install bcrypt npm http GET https://registry.npmjs.org/bcrypt/0.7.3 npm http 304 https://registry.npmjs.org/bcrypt/0.7.3 npm http GET https://registry.npmjs.org/bindings/1.0.0 npm http 304 https://registry.npmjs.org/bindings/1.0.0

bcrypt@0.7.3 install D:\node\nodejsinaction\9\shoutbox\node_modules\bcrypt node-gyp rebuild
