Answer 1

You should use

npm install --save bcrypt

for a proper installation.

By the way to use bcrypt you need python installed. If you want be python-independent use bcryptjs

npm install --save bcryptjs

Answer 2

Have you tried this?

Open powershell with administrator privileges and run this command, then proceed with bcrypt installation.

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

Note: Wait until you see "All Done!" on the powershell window and then proceed to install the module.
