bcrypt is crashing the app while generating salt or hashed password

As per the bcrypt npm documentation I tried to incorporate the package but unable to use bcrypt package in my app, so to test the bcrypt separately I created sample js file which is also crashing on execution without giving any error. Below is the js file which I tried to test. I tried to pass the constant value to hash function, which is also not working.

const bcrypt = require('bcrypt');
async function run(){
const saltValue =await bcrypt.genSalt(10);
bcrypt.hash('12345',saltValue)
.then(result => console.log(result))
.catch(error => console.log(error));
}
run();

Version: node : 9.0.0 npm: '5.5.1' "bcrypt": "^3.0.2",

With nodemon, I am getting message: app crashed - waiting for file changes before starting... in normal execution it is not showing any error.

Update:

If change the bcrypt's async methods with synchronous then it is working fine, 

    const saltValue = bcrypt.genSaltSync(10);
    const hashed = bcrypt.hashSync('12345',saltValue);

I think someone from bcrypt team can answer.

Update: This issue raised on the community and few other developers are facing the same issue, for more information you can refer the link.

bcrypt can be funky sometimes... replace with bcryptjs (far more popular anyway...)

This works just fine:

const bcrypt = require('bcryptjs');

async function run() {
  const saltValue = await bcrypt.genSalt(10);
  bcrypt
    .hash('12345', saltValue)
    .then(result => console.log(result))
    .catch(error => console.log(error));
}
run();

I have node v8.11.4 and bcrypt 4.0.1 version.

I got same error

[nodemon] app crashed - waiting for file changes before starting...

My solution:

I did install bcrypt old version.

npm i --save --save-exact bcrypt@2.0.1

It works fine
