Unable to read typings for "es6-shim" during npm install

Question

I am following deborah kurata's angular2 getting started course on pluralsight and installed node.js and then ran the npm install (after installing cntlm as I am behind a corporate proxy firewall). However I am receiving the following error

Answer 1

If you are behind a proxy you can try this (it worked for me).

Create a .typingsrc file and add the following line with your proxy info:

proxy="http://proxyname:port"

Answer 2

The error is caused due to a connectivity issue.

Your firewall is definitely at the root of the cause.

UPDATE

Some people have solved this through setting a configuration -

npm config set proxy "http://company.com:8000"

Or

npm config set strict-ssl false

Or

npm config set registry "http://registry.npmjs.org/"

You can check out the issue too.

SECOND UPDATE

If you're using VS then you need to set the config from the VS developer console

1. Open the VS developer console
2. Set npm configurations
