Actually, I spend some time reviewing my node_module(s) and can't find _debigger module anywhere.
As well as some require enhancement, it looks like native require is passed to debugger sandbox.

Hi @Mamoru1234

Tnx for the issue and for the repo.
This issue has to do with NodeJS 8. Protractor isn't officially supporting it currently. If you (downgrade to 6.9.x, I use NVM to easily switch) you will see it is working again.

This needs to be something for a future release in which Protractor will support NodeJS 8

@wswebcreation What is the steps to get Node v8 official supported?

Hi @Mamoru1234

I've asked it to the core team. Will post it here if I hear something.

Dupe of #4307

I'm going to go ahead and collapse this to consolidate and track in #4307 @wswebcreation feel free to re-open if you'd like to keep things split out.

I am facing the same issue and unable to use elementExplorer with protractor.

Node version: v8.9.1
Protractor version: Version 5.1.1

$ protractor --elementExplorer
