Error installing bcrypt with npm

Question

I'm unable to install bcrypt 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?

Answer 1

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.

For windows install the following module:

npm install -g node-gyp npm install --g --production windows-build-tools 

Then try to install:

npm install bcrypt
