CodePudding user response：

It is because of the bcrypt module dependency node-gyp. I suggest you use a library bcryptjs which has no dependencies and more downloads.

npm i bcryptjs --save

and dont forget to uninstall

npm uninstall bcrypt --save

On top of that brcypt has more dependecies like python 2.x. This will be also an issue on deployment also. It is better to use libraries with no dependencies. https://www.npmjs.com/package/bcryptjs

CodePudding user response：

You should install node-gyp globally on your pc.

sudo npm install -g node-gyp
then npm install bcrypt
