Hi, I am getting following issue, while installing cypress 3.8.3

cypress@3.8.3 postinstall C:\dev\cy_npm\node_modules\cypress node index.js --exec install

Does your workplace require a proxy to be used to access the Internet? If so, you must configure the HTTP_PROXY environment variable before downloading Cypress. Read more: https://on.cypress.io/proxy-configuration

Otherwise, please check network connectivity and try again:

I have already set my environment variale ie HTTP_PROXY, HTTPS_PROXY and NO_PROXY

As well as I tried with http=<proxy> run cypress. but it didn’t work

Please can you guide
