I updated my node to 16th version, also npm to 8th version but still issue persists

Same for me... I also installed node-pre-gyp locally and used 14.15.3 node version, but it did not change anyting. Seems like many packages that was used here are outdated.

Solution: If you will remove bcrypt package from package.json and try once more without bcrypt it will work. You just have to install bcrypt manually by using "npm i bcrypt" it will download latest version without any errors.

Warning: But be carefull, i am not sure that using latest version of bcrypt good idea here, cause some modules from older bcrypt could be removed/renamed in newer one and you may have problems in future.

Makes me wonder if wether or not I should follow the book @Yuzeyzer

the problem is with bcrypt package, which needs python installed on your pc

I just installed Python from Microsoft store and npm install worked without errors

Or we need to pick another bcrypt package from npm

I got this to work for me. I needed to use node version 12.14.1, the current version as of the books publishing. I am using windows 11.
Try:
Uninstall node.js

Install nvm-windows: https://github.com/coreybutler/nvm-windows#installation--upgrades

In the terminal type nvm install 12.14.1 Followed by nvm use 12.41.1

then clone the repo and use npm install.

This also worked for me, but a couple notes:

1. I think you meant nvm use 12.14.1 .
2. Windows users, make sure you are running your terminal or IDE in administrator mode, otherwise nvm use 12.14.1 will not work.
3. For some windows users, make sure to navigate to your C:\Program Files or C:\Program Files(x86) directory to ensure the nodejs folder was completely deleted when you uninstalled node.js, otherwise you will get an "exit status 145: The directory is not empty." error when running nvm use 12.14.1.

I ran into the same issue while trying to follow the book on a Debian (bullseye) vm that did not have python installed. I was able to solve it by replacing bcrypt with bcryptjs (latest version) in the package.json. We'll see if it comes back to bite me later, but so far so good.
