From the error message, tunneling socket could not be established, cause=read ECONNRESET, it looks like you’re behind a proxy.
This tends to be an issue when the proxy is set to an https url, but should be http

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