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:

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

Answer 1

全局安装node-gyp包，然后重试npm i bcrypt

npm i -g node-gyp

Answer 2

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

Answer 3

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.

Answer 4

I was try to write npm i -g bcrypt and then write npm i bcrypt . Now it's working for me!

Answer 5

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
