All pip install attempts are met with SSL error

[flycast]

Using Windows...
Python 3.6.3
When I attempt to install anything using:

C:\Users\Eric>pip install ssl
Collecting ssl
Could not fetch URL https://pypi.python.org/simple/ssl/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777) - skipping
Could not find a version that satisfies the requirement ssl (from versions: )
No matching distribution found for ssl

I have found the trusted--host settings but this affects everything that I do in python. I have pyCharm and installing packages fail there as well for the same issue.

How do I resolve this issue at it's root rather than using trusted--host workaround?
