Trouble with node bcrypt installation - node.js

Question

I am learning sails.js. So I just want to encrypt password using node module bcrypt.
npm install bcrypt is the command what I use to install bcrypt modules, I came to know that it has many dependencies, I intalled node-gyp as well npm install -g node-gyp
Can anyone suggest how can I get it resolved?

Answer 1

I had pretty much the same problem on Ubuntu 13.10, the error log looked the same and the bcrypt installation stopped at node-gyp rebuild. After some searching and updating node and npm I still had the same issues.
I found a solution finally here: https://github.com/ncb000gt/node.bcrypt.js/issues/90 and the problem was the ~/.node-gyp directory which had unsufficient access rights and simply deleting it did the trick. This is where gyp stores headers and other build files during compilation and if it's gone, gyp will just recreate it.

Try to install global windows build tool if you are using windows,
follow this link bcrypt install instruction
npm install --global --production windows-build-tools
