Does anyone know how to fix it? been trying to fix it for couple days now, help is much appreciated!

Try to use bcrypt.js module instead of bcrypt which is an update/latest npm module.

Run npm install bcryptjs and then npm install

First make sure you are not uploading the node modules folder and that the npm install command is working on the instance.

https://github.com/kelektiv/node.bcrypt.js/wiki/Installation-Instructions

This problem is related to node-pre-gyp. A dependency of bcrypt.

For AWS Elastic Beanstalk When deploying to Elastic Beanstalk running Node 8.x, node-gyp doesn't have sufficient permissions to write to the tmp directory. bcrypt won't install and the application deployment will fail.

A workaround is to add a .npmrc file to the root of your project that will force node-gyp to run as root and allow the installation to complete. File contents for .npmrc:

# Force npm to run node-gyp also as root, preventing permission denied errors in AWS with npm@5 or @6
unsafe-perm=true

Another alternative (Perhaps the more right way) is to make .ebextensions file with code:

.ebextensions:00_change_npm_permissions.config:

  "/opt/elasticbeanstalk/hooks/appdeploy/post/00_set_tmp_permissions.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/usr/bin/env bash
      chown -R nodejs:nodejs /tmp/.npm

This will give you sufficient access to run node-gyp
