Node.js Question

Error installing bcrypt with npm

I'm unable to install

using
npm
on my machine because I encounter the following errors. I have been troubleshooting the issue without much luck. Can you recommend any steps to diagnose or fix the problem so I can run
npm install bcrypt
successfully?

Someones-Macbook:node_modules Cody$ npm install bcrypt
npm WARN package.json grunt-contrib-htmlmin@0.1.3 No README data

Answer

The easy solution is just switch from the "bcrypt" npm module to bycryptjs or bcrypt-nodejs. It's the exact same API, but pure JS so no native add-ons to deal with.

npm install --save bcryptjs && npm uninstall --save bcrypt

Then change your require calls to "bcryptjs", but all your code otherwise can be unchanged.

Long term, I suspect at the moment bcrypt may not be ready for node v0.12.0 yet, but if not it will eventually be updated and ready.
