npm unable to install scrypt. node-gyp rebuild

Question

I want to run a blockchain application, but I got this error.

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR. scrypt@6.0:3 install: node-gyp rebuild
npm ERR! Exit status 1
npm ERR!
npm ERR. Failed at the scrypt@6.0.3 install script.
npm ERR. This is probably not a problem with npm.

There is likely additional logging output above.

I have tried deleting node_modules, npm cache verify and npm install again. I have uninstalled and reinstalled npm and nodejs . My npm version is 6.12.0 and node version v12.13.0

From this link:

I've solved this using the following steps

npm install --global --production windows-build-tools
node-gyp configure --msvs_version=2015
npm config set python /path/to/executable/python2.7
npm install web3 --save

And also, I think that you can follow steps to fix node-gyp:

Answer 2

Command line developer tools will be needed to recompile:

macOS

https://developer.apple.com/downloads/index.action Download 'Command Line Tools for Xcode 11' You will be asked for your Apple Developer Login during the installation process.

Ubuntu

$ sudo apt-get install build-essential

Windows 10

$ npm install -g windows-build-tools

Answer 3

Believe or not, use: sudo npm... It worked for me

Answer 4

I know this is an old one, but for anyone hung on this one now, what solved this for me was downgrading to node v10.24.1 & npm v6.14.12. Seems to be an issue with newer node versions.

Answer 5

sudo apt-get update -y
sudo apt-get remove -y gyp
sudo apt-get install -y curl bzip2 build-essential g++ python3 git make gcc gcc-multilib node-gyp
sudo apt-get install -y pkg-config xserver-xorg-dev libxext-dev pkg-config libxi-dev libglu1-mesa-dev libglew-dev
sudo npm install prebuild-install node-pre-gyp node-gyp -g

if show already exist then use --force flag while installing npm package

if then also not solve then try install package using "sudo npm i "
