I recently tried to install a library using Pip, and I received this error message. I am unable to install any packages, as the same error message keeps popping up.
I notice this problem in both my main enviroment, and my venv Virtual Environment.
Any help will be much appreciated.

I was able to fix the problem by hard-coding in a 1, instead of having CERT_NONE being passed to verify_mode.
The error message gave me the location of the code:

super(SSLContext, SSLContext).verify_mode.__set__(self, 0)

I swapped the variable value -> 1

super(SSLContext, SSLContext).verify_mode.__set__(self, 1)
