Unable to log the hash

I installed bcrypt on my Mac, at least I think I did because I can see it in the node_modules folder on my system. So, /shrug/.

Anyway, here is my result from trying to follow along with Chalkers in this video:

My code:

const unsecurePlainTextPassword = 'password';
const bcrypt = require('bcrypt');
const saltRounds = 10;
const myPlaintextPassword = 's0/\/\P4$$w0rD';
const someOtherPlaintextPassword = 'not_bacon';
bcrypt.genSalt(saltRounds, function(err, salt) {
    bcrypt.hash(unsecurePlainTextPassword, salt, function(err, hash) {

My error in the VSC terminal:

Trevors-iMac:~ trevormaltbie$ node sandbox.js
    throw err;

Error: Cannot find module '/Users/trevormaltbie/sandbox.js'

Also, this video is a bit outdated. The README in bcrypt is updated quite a lot since this was made. Not sure I copied the write code? It may be time to re-do this video with updated bcrypt.

This was my install output:

Trevors-iMac:~ trevormaltbie$ python --version
Python 2.7.16
Trevors-iMac:~ trevormaltbie$ python2 --version
-bash: python2: command not found
Trevors-iMac:~ trevormaltbie$ npm install bcrypt --python=python2

FIXED: Deleting the workspace - opening it again and installing bcryptjs instead of bcrypt has worked.

--I had these same issues before trying bcryptjs
