“There was a problem confirming the ssl certificate” using pipenv install

Question

I'm trying to use pipenv in a new Django project. However, if I try to pipenv install django , I get an error confirming the SSL certificate:

Kurts-MacBook-Pro:wemap kurtpeek$ pipenv install django
Installing django...
Collecting django
  Could not fetch URL https://pypi.python.org/simple/django/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping

Error:  An error occurred while installing django!
  Could not find a version that satisfies the requirement django (from versions: )
No matching distribution found for django

I've recently run a brew upgrade ; here are my Pipenv and Python versions:

Kurts-MacBook-Pro:wemap kurtpeek$ pipenv --version
pipenv, version 2018.7.1
Kurts-MacBook-Pro:wemap kurtpeek$ python --version
Python 3.7.0

I've tried the answer of Not able to install Python packages [SSL: TLSV1_ALERT_PROTOCOL_VERSION] but this essentially didn't do anything as my pip version was already up-to-date:

I am running MacOS Sierra version 10.12.6, so this does indeed seem to be caused by the TLS 1.0 deprecation issue described in 'pip install' fails for every package ("Could not find a version that satisfies the requirement") . But how to remedy this?

Answer 1

In the end, I solved this by upgrading my Macbook Pro to macOS High Sierra (Version 10.13.6). Now I can pipenv install django :

Kurts-MacBook-Pro:wemap kurtpeek$ pipenv install django
