How to rectify error WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available?

Whenever I use pip3 for eg I did pip3 install virtualenvwrapper-win

I get WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

Also for this specific module virtualenvwrapper I am getting

ERROR: Could not find a version that satisfies the requirement virtualenvwrapper-win (from 
versions: none)
ERROR: No matching distribution found for virtualenvwrapper-win

But installing anything with pip works fine it's just pip3 that's not working.

I searched askUbuntu for this and found this but the accepted answer to this is not working for me. More specifically if I do sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev

I get E: Unable to correct problems, you have held broken packages.

Please help me to fix pip3.
