How to install bcrypt on Windows 10

Question

I want to install bcrypt in my Express project. I have followed the instructions provided in this page for windows users. I just run the given command npm install --global --production windows-build-tools and it was successfully like shown in the picture below.

But still when I run npm i bcrypt I get the following error:

node-pre-gyp WARN Using needle for node-pre-gyp https download node-pre-gyp WARN Tried to download(404): https://github.com/kelektiv/node.bcrypt.js/releases/download/v3.0.3/bcrypt_lib-v3.0.3-node-v64-win32-x64-unknown.tar.gz node-pre-gyp WARN Pre-built binaries not found for bcrypt@3.0.3 and node@10.15.0 (node-v64 ABI, unknown) (falling back to source compile with node-gyp) gyp ERR! stack Error: Can't find Python executable "python2.7", you can set the PYTHON env variable. ....more errors

I managed to set Python path from this answer here. Now I get this error:

node-pre-gyp WARN Using needle for node-pre-gyp https download node-pre-gyp WARN Tried to download(404) https://github.com/kelektiv/node.bcrypt.js/releases/download/v3.0.3/bcrypt_lib-v3.0.3-node-v64-win32-x64-unknown.tar.gz

To enable parallel build, please add the "/m" switch. blowfish.cc bcrypt.cc bcrypt_node.cc win_delay_load_hook.cc

I don't know it works or not. `npm cache clean --force` – Nuriddin Kudratov Jan 15 '19 at 21:14 — Nuriddin Kudratov, Jan 15 '19 at 21:14

This fixed it for me right away! Thank you. (this should be the accepted answer in my opinion -- the question is how to get bcrypt installed on Windows, not "what is an alternative to bcrypt on windows") – Matt Oestreich Feb 13 '20 at 13:46

After so much struggle of installing bcrypt in windows 10, I finally gave up and decided to install alternative package bcrypt.js which is optimized bcrypt written in JavaScript with zero dependencies. Hope this will help someone who is facing similar issue.

Just use npm i bcryptjs instead of npm i bcrypt

you are either trying to download a package which is no longer present in the GitHub of bcrypt OR the package has moved. Either way, bcrypt is primarily a python package. Using npm, it forces you to use python 2.7 while there is a perfectly functional version of bcrypt for python 3(used it in the past).

I recommend using a node-centric package instead of bcrypt or detaching its use from npm and running it separately with python 3.

Thanks for response! But what do you mean by node centric package? Which one should I use? – Nux Jan 16 '19 at 19:15

In my case, the environment variable was a mess.

I've to clean the environment variable regarding node-gyp. npm life-cycle module was dependent on node-gyp and this was present in the path as node-gyp

Also i noticed there was multiple entry for python one is for 2.7 and another is 3.x I kept them both and make sure npm used python 2.7

Then i installed node-gyp globally and finally npm i bcrypt

Sometimes npm i -g node-gyp command not works. In my case I just run the command npm i -g node-gyp and tried to uninstall and install again the bycript and it works.

Delete the bcrypt

npm uninstall bcrypt

Download bcrypt again

npm install bcrypt
