npm - https proxy error using nodeJS

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.
