Anyone else seen this? Working with python 2.7.13 on windows. I'm behind an SSL Intercept and it took me forever to get past the ssl errors on python and pip by installing ceritfi and adding our own cert to the cacert.pem. 

BUT this doesn't work in virtualenv, no matter what I try(sames steps) I still get the error - 

">pip install flask
Collecting flask
 Could not fetch URL <https://pypi.python.org/simple/flask/>: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE\_VERIFY\_FAILED] certificate verify failed (\_ssl.c:581) - skipping

Wondering if anyone has seen this and gotten it to work - thanks!
