Troubleshooting with nodejs and npm

I got error when I tried to install rasa-nlu-trainer
$npm i -g rasa-nlu-trainer

error:

npm http GET https://registry.npmjs.org/express
npm ERR! Error: SSL Error: CERT_UNTRUSTED
npm ERR!     at ClientRequest.<anonymous> (C:\Program Files\nodejs\node_modules\npm\node_modules\request\main.js:409:26)
npm ERR!     at ClientRequest.g (events.js:185:14)
npm ERR!     at ClientRequest.EventEmitter.emit (events.js:88:17)
