Does Protractor 4 has any dependency? - protractor

Question

I have been using protractor 3.3.0 and finally decided to move up to V4. I am behind a firewall, so using proxy setup. That setup works fine for v3.3.0, but I am not able to download any of V4. It always results in ECONNREFUSED with error
error on last attempt: Error: tunneling socket cound not be established, cause connect ECONNREFUSED <ip>:<port>"
is there any difference on how to download Protractor V4 and above? I have tried
npm install protractor (my package.json had "protractor": "^4.0.0")
npm install protractor (my package.json had "protractor": "4.0.4")
npm install protractor#4.0.0
npm install protractor#4.0.4
When I couldn't install it, I moved back to v3.3.0.. my package.json has "protractor": "^3.2.2")

The error you are seeing is a common one when connecting through proxies. Please see here for the discussion
And yes there are new dependencies/new versions of old dependencies in Protractor#4.0.4 which will trigger new downloads.
