Solution for ENOTFOUND getaddrinfo ERROR :

Scenario 1 :
If you have username and authentication code for proxy then use execute below command:
npm config set proxy http://userName:passwordOrAuthenticatioCode@proxy-domain.com:port
npm config set https-proxy http://userName:passwordOrAuthenticatioCode@proxy-domain.com:port
npm config set strict-ssl false

OR

Scenario 2 :
If you dont have username and authentication code for proxy then execute below command:

npm config set proxy http://proxy-domain.com:port
npm config set https-proxy http://proxy-domain.com:port
npm config set strict-ssl false

we executed npm config set strict-ssl false command, to resolve error :

UNABLE_TO_GET_ISSUER_CERT_LOCALLY
