bcrypt doesn't work in seed file

[liemdo]

When I run the seed, the script exits immediately when it hits the bcrypt.hash function

module.exports = {
  up: function (queryInterface, Sequelize) {
   console.log('before hashing');
   bcrypt.hashSync('password', 10);
   console.log('after hashing');

after hashing doesn't show up in the console and the script exits right before that.

Sequelize [Node: 8.2.1, CLI: 2.8.0, ORM: 4.3.0]

Using environment "development".
