You can do npm update <package name> to update specific pacakage. To update it globally you can use -g. To update all the outdated packages you can use just npm update
To update to specific version use '#packageversionname' after package as like npm update express#1.0.2
If you are still getting error try uninstalling it first and installing it to specific version

In this issues you can just install bcrypt-nodejs or bcryptjs instead of bcrypt by the following commend:
npm install --save bcrypt-nodejs && npm uninstall --save bcrypt
After that, you just call this methode in the file server.js like this:
var bcryptNodejs = require('bcrypt-nodejs'); //Or bcryptjs

From your warning message, node-uuid is deprecated so just uninstall it and use uuid instead.
npm WARN deprecated node-uuid#1.4.8: Use uuid module instead
Try this way,
npm uninstall --save node-uuid
npm install --save uuid
