NodeJS behind proxy

I was getting this message when trying to run node js:

D:\Temp>npm install vss-web-extension-sdk
npm ERR! Windows_NT 10.0.14393
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "install" "vss-web-extension-sdk"

npm ERR! network 'proxy' config is set properly.  See: 'npm help config'

npm ERR! Please include the following file with any support request:

Well I am behind a Corporate enterprise, so I can the following command:

npm config set proxy http://[username]:[password]@[proxyServerAddress]:[proxyPortNumber]
and also ran
npm config set https-proxy http://[username]:[password]@[proxyServerAddress]:[proxyPortNumber]

Notice the same address on the first and second entries, that is normal. Just telling the https traffic to go through the same proxy.

Now I get this:

D:\Temp>npm install vss-web-extension-sdk
