Error when running my fork of truffle-core: can't find module truffle-core/run?

[roschler]

I'm trying to make my own custom build of the truffle-core repo. I've forked the repo and made a Node.JS configuration in IntelliJ's WebStorm IDE. When I run "npm start" I get the following exception:

internal/modules/cjs/loader.js:596
    throw err;
    ^

Error: Cannot find module '/home/robert/Documents/GitHub/ME/truffle-core/run'

    at startup (internal/bootstrap/node.js:238:19)
    at bootstrapNodeJSCore (internal/bootstrap/node.js:572:3)
Waiting for the debugger to disconnect...

What do I need to do to get a runnable/debuggable environment using this repo?

Got past that error. I needed to specify index.j as my starting Javascript file. Now I'm having a problem with it finding "./lib/config":

Debugger attached.
