Not sure the exact issue, looks like it doesn't like the objectstream module. Maybe try npm install again? Maybe npm update for an outdated module?

[kawikakanaka]

I got the same error, along with some others during the npm install:

[tannerjt]

Can you specify which version of Node you are running? In your terminal or command prompt, type node -v

[tannerjt]

It looks like the problem is coming from objectstream

var EventEmitter = process.EventEmitter;
util.inherits(ObjectDeserializeStream, EventEmitter);

My guess is that process.EventEmitter is null. Can you try running node in command line and typing process.EventEmitter and see what is returned?

[tannerjt]

For now, you can try this workaround. In node_modules/objectstream/lib/objectstream.js, replace:

var EventEmitter = process.EventEmitter

with

var EventEmitter = require('events');

Let me know if that works. If so, I'll submit a pull request to the objectstream library

[kawikakanaka]

That worked! Thanks tannerjt!

My npm version is 4.1.2
node version 7.7.4.0 (32bit)
Windows 10

[tannerjt]

That's great, I'll let the maintainer of the objectstream library know
