node modules installation ERROR

[mustafaKamal-fe]

on initial installation [npm i ] or [yarn install] the (bcrypt) package is causing the installation process to fail. however, installing it on a separate line yeilds with 1926 vulnerabilities:

Looks like it doesn't work in node 12. I didn't have installation problems once I switched to node 10 using nvm.

Looks like it doesn't work in node 12. I didn't have installation problems once I switched to node 10 using nvm. its a thing to maintain valuable yet a bit outdated courses.

I faced this issue in master branch and solved it by changing bcrypt package to bcryptjs like lesson branches in package.json file: remove "bcrypt": "^3.0.2" and add "bcryptjs": "^2.4.3" in user.model.js file: replace the bcrypt package to be bcryptjs

[bbernag]

Fixed installing "bcrypt": "^5.0.0"
