[Jack89ita]

Same here

[recrsn]

Install dependencies. It's mentioned everywhere in the README

[rkarami]

Facing same issue.
Old version works fine.

[Akshay-Rana-Gujjar]

version 3.0.1 works fine

[andersonmendesdev]

Version 3.0.2 same problem.

[zabahey]

I think we should follow the instruction to install this library. Please click here

Same issue, I noticed I could not hash passwords for my users after I updated the node version.

Big security issue

[orgertot]

I installed the dependencies but still no prebuild ...

[zhuhang-jasper]

tried?
npm install --global --production windows-build-tools

node-pre-gyp WARN Using request 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 [email protected] and [email protected] (node-v64 ABI, unknown) (falling back to source compile with node-gyp)

@3.0.2 works since node-v64 is released, 3.0.3 does not have this version under releases.

[XadillaX]

@multinerd I have the same issue. Why there's no 3.0.3's v64?

[djanowski]

3.0.2 does work on Node 10 / macOS.

[ACPK]

@djanowski - 3.0.2 did not work on my Mac.

[nezlicodes]

Fixed it by installing the dependencies: https://github.com/kelektiv/node.bcrypt.js/wiki/Installation-Instructions.

There is also this the bcrypt alternative that you can consider. It is optimized in JavaScript with zero dependencies.

[diamond95]

it works for me after installing visual studio 2019( c++ desktop development ), python 3.8.0 and
npm install -g node-gyp
npm install --g --production windows-build-tools
npm install bcrypt

[krishheii]

Please try this it will definitely work, this error occur because you are not using a stable version of node
npm install --save bcryptjs && npm uninstall --save bcrypt

[edgargaza]

@diamond95 answer worked for me, just pointing it out!

[vjainlion]

Steps:-
1 npm install --global --production windows-build-tools(from the shell as administrator)
2 npm i bcrypt.

[theclabs]

it's a permissions issue in AWS
try
cd project
chmod 777 node_modules
npm install bcrypt -save
chmod go-w node_modules

or
cd proyect
echo "# Force npm to run node-gyp also as root, preventing errors in AWS with npm@5 or @6" >> .npmrc
echo "unsafe-perm=true" >> .npmrc
npm install

You can check the list of pre-built releases here: https://github.com/kelektiv/node.bcrypt.js/releases

One should match your OS and Node version.

As of today, on Windows, only 3.0.6 is pre-built for Node 12.x. That's not ideal but at least you can avoid downloading the MS dependencies by fixing the version in your package.json.

[elsoftsolutions]

This is due to unstable version of Node version.

1. Install stable version of node with
   sudo npm cache clean -f
   sudo npm install -g n
   sudo n stable

1. Make sure you follow the instructions here: https://github.com/kelektiv/node.bcrypt.js/wiki/Installation-Instructions#ubuntu-and-derivatives---elementary-linux-mint-etc

2. install package with root permission:
   sudo npm install --unsafe-perm=true --allow-root

[PulkitAgg]

I was facing this issue because of my node js version 12.8.3. I just changed my node version to 12.4.1. And then try to install bcrypt using npm i bcrypt. Now its working fine for me.

Check/Download Different Node.js version from this Link

Try installing node-pre-gyp again then npm installing any missing modules.
This worked for me.

npm i node-pre-gyp
