npm not working - "read ECONNRESET"

Remove your proxy settings at home and switch on at Office networks, This may be irritating, But It worked for me:

npm config set proxy http://xxx.xxx.xxx.4:8080   
npm config set https-proxy http://xxx.xxx.xxx.4:8080

and

npm config rm proxy   
npm config rm https-proxy

You may also need to specify the proxy server/port, in some environments the system settings for proxy are not enough for npm to work.

    npm config set proxy "http://your-proxy.com:80"

You may want to check your NPM proxy settings and perhaps remove it.

npm config get proxy
npm config rm proxy
npm config rm https-proxy

One might expect a fresh install of NodeJS+NPM would not have a proxy configured. Strangely enough, mine did come with a proxy defined, pointing to an IP and port 3128. Removing the proxy did the trick.

use

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

so that npm requests for http url instead of https.

and then try the same npm install command
