This is because of npm is not compatible. Try to update npm to latest version by

‘npm update’

Then again fire ‘npm install’

It will work possibly Thank you

i also face same problem.i found solution for that. bcrypt required C++, python and node-pre-gyp. sudo apt-get install g++ sudo apt-get install -y build-essential python npm install node-pre-gyp for more details check : https://github.com/kelektiv/node.bcrypt.js/wiki/Installation-Instructions#ubuntu-and-derivatives---elementary-linux-mint-etc
