Running “npm install” on an enterprise workstation can often trigger an avalanche of errors. Running the below commands helps point NPM at the corporate proxy server to resolve the issue.

Commands
npm config set strict-ssl false
npm config set registry "http://registry.npmjs.org"
npm config set proxy=http://proxy.company.com:8080
npm config set https-proxy=http://proxy.company.com:8080
