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! [email protected] install: node-gyp rebuild
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] 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
