npm - https proxy error using nodeJS - node.js

Question

This is the error, doesn't make me install nothing:
npm WARN invalid config https-proxy="http:"
npm WARN invalid config Must be a full url with 'http://'
I try a lot of things:
uninstall/install node and npm
clean npm cache
npm config delete https-proxy
set npm ssl to false
npm config set registry http://registry.npmjs.org/
tried to override it with npm config set https-proxy http://proxy.company.com:8080
open and change manually npmrc global and local files
I get response doing ping to registry.npmjs.org and google.es in console.
Even I uninstall all node and make a new compilation and error persist.
npm config get https-proxy
and
npm config get http-proxy
returns me null both.

Answer 1

It was a connection problem.
I remember thatI played with proxy configuration by mistake like this :
npm config set proxy http://localhost:8080/
npm config set https-proxy http://localhost:8080/
npm config set strict-ssl false
which made npm client attempts to hit localhost:8080 to pull the module rather than the correct internet endpoint.
so after couple of days of frustration i visited this link
https://docs.npmjs.com/cli/config
then run
npm config edit
which opened a file inside that file i removed those three lines i added above , then everything worked fine.
