Unable to read typings for “es6-shim” during npm install

问题

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

> product-management@1.0.0 postinstall c:\Users\test\Documents\Visual Studio 2015\Projects\Angular2
> typings install

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"

Source of my answer

回答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

I solved creating .typingsrc file in the same folder, with the following content:

proxy = http://username:password@ip:port
https-proxy = http://username:password@ip:port

The words "username", "password", "ip" and "port" should be replaced with the values of your proxy.

回答4:

I solved following the link in the Pere Page's answer. I've created a .typingsrc file with these lines:

{ "proxy" : "http://myproxy:port/", "rejectUnauthorized" : false }

回答5:

Create .typingscr file in your project folder parallel to package.json and put below line. Remember to put it in ini format not in json format.

rejectUnauthorized = false

I am using this behind corporate environment without any proxy setting and it worked for me, hope will work for you.
