Migration Guide from v2 to v3?

[SammyIsra]

Hi all,

I upgraded Hubot from v2 to v3 as an attempt to fix NPM Audit issues, however, since then I have not been able to run npm ./bin/hubot to run the project, as I get the error:

C:\<path to project root>\bin\hubot:5
npm install
    ^^^^^^^

SyntaxError: Unexpected identifier
    at new Script (vm.js:51:7)
    at createScript (vm.js:136:10)

    at Function.Module.runMain (module.js:703:10)
    at startup (bootstrap_node.js:193:16)

Additionally, running npm install show the following peer dependency warnings:

npm WARN [email protected] requires a peer of [email protected] but none is installed. You must install peer dependencies yourself.
npm WARN [email protected] requires a peer of [email protected] but none is installed. You must install peer dependencies yourself.
npm WARN [email protected] requires a peer of [email protected] but none is installed. You must install peer dependencies yourself.
npm WARN [email protected] requires a peer of [email protected] but none is installed. You must install peer dependencies yourself.

Before trying to fix those errors, I wanted to try my hand in finding some guidance here.

I haven't found any resources on how to upgrade to v3, or what's really different about it, so my attempt to upgrade was really brute force-ish.

For an example of what versions changed, I have the following request open on my own project: SammyIsra/fred#27

I think you're supposed to just execute bin/hubot to start the app.
