Javascript Question

using a pure-JavaScript implementation of bcrypt

Hi there I am using meteor js which is great but i am getting this message on my console .

W20161001-16:02:18.321(1)? (STDERR) Note: you are using a pure-JavaScript implementation of bcrypt.
W20161001-16:02:18.322(1)? (STDERR) While this implementation will work correctly, it is known to be
W20161001-16:02:18.322(1)? (STDERR) approximately three times slower than the native implementation.
W20161001-16:02:18.322(1)? (STDERR) In order to use the native implementation instead, run
W20161001-16:02:18.323(1)? (STDERR)
W20161001-16:02:18.323(1)? (STDERR) meteor npm install --save bcrypt
W20161001-16:02:18.323(1)? (STDERR)
W20161001-16:02:18.323(1)? (STDERR) in the root directory of your application.

I have node-gyp install globally, remove bcrypt from the packages file and running

meteor npm install --save bcrypt

to get this error

Dont know what to do next really i am really new to meteor. I am on windows 10 using shell. node v4.6.0 Any help would be great.


You need to install an appropriate build environment to compile node addons (such as bcrypt). This means installing Python 2.7.x and some sort of toolchain.

You could try the windows-build-tools module which will try to install both Python and the minimum compiler environment via npm (or you can install the minimum compiler environment manually from here), otherwise for just the toolchain part there is always Visual C++ Express/Community (Desktop version).
