If you are working behind a proxy in a "windows" domain, add the domain name into the proxy url:

npm config set proxy http://domain%5Cuser:password@proxy.company.com:8080
npm config set https-proxy http://domain%5Cuser:password@proxy.company.com:8080

You need to encode the backslash as a http uri string: %5C

If there are special characters in your username or password, it is necessary to encode these character as well. Keep in mind that these critical informations are stored as plain text in the npm config file (%HOME%\.npmrc). It could also be necessary to point the npm registry to the http source:

npm config set registry "http://registry.npmjs.org"
npm config set strict-ssl false
