Mac users: If you are running macOS/OS X version 10.12 or older, you need to upgrade to the latest pip (9.0.3) to connect to the Python Package Index securely:
curl https://bootstrap.pypa.io/get-pip.py | python Pip 9.0.3 supports TLSv1.2 when running under system Python on macOS < 10.13. Official release notes: https://pip.pypa.io/en/stable/news/ Context: As PSF blogged last year https://pyfound.blogspot.com/2017/01/time-to-upgrade-your-python-tls-v12.html , on June 30, 2018, Python.org sites are going to entirely stop supporting TLS versions 1.0 and 1.1, because our CDN provider is deprecating support for those versions. We are launching the new PyPI (in beta at https://pypi.org) this month and replacing the legacy PyPI (https://pypi.python.org). Here's the beta announcement for the new PyPI: https://pyfound.blogspot.com/2018/03/warehouse-all-new-pypi-is-now-in-beta.html Warehouse, the codebase for the new PyPI, does not support TLS 1.0 or 1.1. We're warning our users early with this message. Also, as of late March, the Python Package Index has started doing brownouts of the deprecated TLS versions. For some portion of each hour, anyone attempting to access PyPI with TLSv1.0 or TLSv1.1 will get a 403 response with an informative error. As we get closer to the deadline, we will be ramping up the amount of time the endpoint is down for the deprecated TLS versions. The ultimate goal is to have it be 100% unavailable on and after April 8th, prior to the final deadline (because we can give a good error message -- once June 30th hits, it will just be an uninformative OpenSSL error).
