npm install bcrypt, gyp ERR! python

Question

on windows 10 node:v6.7.0, npm:v4.0.1 node-gyp:v3.4.0, I am trying to npm install --save bcrypt that I face these errors. this is where I have both, python27 and python35-32 in my path.

D:\myApp\node_modules\bcrypt>if not defined npm_config_node_gyp (node "C:\Users\myname\AppData\Roaming\npm\node_modules\npm\bin\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild )  else (node "" rebuild )
gyp ERR! configure error
gyp ERR! stack Error: Python executable "C:\Users\myname\AppData\Local\Programs\Python\Python35-32\python.EXE" is v3.5.2, which is not supported by gyp.
gyp ERR! stack You can pass the --python switch to point to Python >= v2.5.0 & < 3.0.0.
gyp ERR! stack     at failPythonVersion (C:\Users\Amirhossein\AppData\Roaming\npm\node_modules\npm\node_modules\node-gyp\lib\configure.js:454:14) ....

I tried to install with npm install --save --python=phyton2.7 bcrypt

it seems ok, but finished installing with lots of warnings:

D:\myApp\node_modules\bcrypt>if not defined npm_config_node_gyp (node "C:\Users\myname\AppData\Roaming\npm\node_modules\npm\bin\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild )  else (node "" rebuild )

will it work correctly? what is the proper way of installing bcrypt? should I modify config at node-gyp?

If you are open to ditching bcrypt, I would suggest to use bcryptjs, which is compatible with bcrypt with zero dependencies. Yes, that will incur a performance hit, but if you're OK with that, it will get you out of node-gyp rebuild hell.

You could also install Python2.x in your Operating System and run:

npm config set python /path/to/python2.x

This solved the problem for me, hope is helpful to somebody.

Easiest solution: ditch python bcrypt and use bcrypt-nodejs instead: https://github.com/shaneGirish/bcrypt-nodejs

is this functional equivalent ? – Amir-Mousavi Nov 18 '16 at 21:02

IMHO that is fine if you don't care about performance (yes I know the purpose of bcrypt, but there is still an unnecessary performance hit when doing bcrypt in pure javascript). – mscdex Nov 18 '16 at 21:02
`npm WARN deprecated bcrypt-nodejs@0.0.3: bcrypt-nodejs is no longer actively maintained. Please use bcrypt or bcryptjs. See https://github.com/kelektiv/node.bcrypt.js/wiki/bcrypt-vs-brypt.js to learn more about these two options` – Chloe Oct 10 '19 at 19:33
