Node.js nie może zainstalować gulp

Zainstalowałem node.js i próbowałem użyć npm do zainstalowania gulp dla mojego programowania, ale pojawia się błąd dla gulp:

$ npm i gulp browser-sync gulp-sass --save-dev
npm ERR! code UNABLE_TO_GET_ISSUER_CERT_LOCALLY
npm ERR! errno UNABLE_TO_GET_ISSUER_CERT_LOCALLY

Uwaga: myślę, że mój laptop ma problem z certyfikatem. Mam ten sam problem, próbowałem zainstalować Flask dla Pythona ...
