Installing scrypt using npm on windows is giving following error. The build is failing due to node-gyp

Answer 1

From github documentation node-Gyp is listed as pre-requisite as it is required to build scrypt . Make it sure to install node-Gyp

using npm install -g node-gyp

For successfull working of this plugin you will also need to install all the required tools and configurations using Microsoft's windows-build-tools

using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator). for other options and alternatives follow node-gyp documentation

Before installing scrypt Follow installation instructions given at github

Answer 2

first you need to install windows-build-tools

run this command first

> npm install --global --production windows-build-tools

Answer 3

For NodeJS 10.5.0 and higher

My answer could be a little bit out of topic, but I encountered a similar error with the installation of the scrypt library for NodeJS v12 : during the compilation of the C/C++ modules with node-gyp a lot of compiling warnings and errors appear.

Though, there is an elegant solution.

Since version 10.5.0 NodeJS has a crypto.scrypt(...) function, which (with several other functions from crypto module) could cover almost all real use-cases.

So, a decent solution could sound like: Remove scrypt -package from your code and use the appropriate functions from the crypto -native module .

Sadly, but in most cases it is not the best solution for a real business
