It looks like it’s failing while trying to pull files from the Internet. Is your network connection stable?

You encounter an error due to your system ssl configuration that cannot permit ssl verification. You probably are behind a proxy or a vpn that needs some more configuration at ssl authentication level, like adding ssl certificates.

You can bypass ssl verification at your own risks by following instructions provided at this thread : https://stackoverflow.com/questions/25981703/pip-install-fails-with-connection-error-ssl-certificate-verify-failed-certi

thanks everyone for your support! The problem was, my router's cache memory was full which led to unstable internet connection. All your comments helped me to successfully diagnose and fix the issue.
