So everything worked fine in truffle 4.1.14, but when I upgraded to 5.0.0 I got this error:

TypeError: source.setEngine is not a function
  at Web3ProviderEngine.addProvider (node_modules/web3-provider-engine/index.js:71:10

I'm using this require:

const ProviderEngine = require('web3-provider-engine')

And this is the code that is cusing the error:

var engine = new ProviderEngine()


Is it a bug with web3 provider engine? Any help would be great thanks!
