I am not able to install any Python libraries. I am using pip 9.0.1 and python 2.7. I am getting the following error:

EN-NishantS:~ 8417$ pip install presto-python-client Collecting presto-python-client Could not find a version that satisfies the requirement presto-python-client (from versions: ) No matching distribution found for presto-python-client

On running with pip install -vvv I am getting the following:

  • This is probably the root cause: TLSv1.2+ is required for url: https://pypi.python.org/. (TLS is the s in https). How old is your system? Commented Apr 9, 2018 at 13:55

  • @nish sorry saw the message too late. Did you install pip via brew? You might want to update it via brew or try "sudo easy_install -U pip" instead? Commented Apr 9, 2018 at 14:11

    @nish Sierra is not old, there should be no problems with TLS v1.2 support unless something is installed or configured incorrectly. Commented Apr 9, 2018 at 14:46

    I faced the same error recently. Got resolved by installing pip as follows: curl https://bootstrap.pypa.io/get-pip.py | python. See this Commented Apr 10, 2018 at 8:27

On Mac you can do

sudo curl https://bootstrap.pypa.io/get-pip.py | python

doesnot work for me. I have mac 10.10.5. I am getting permission error [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pip-7.1.2.dist-info/DESCRIPTION.rst'
Can you please include an explanation?

I was having the same issue today trying to install Django.

I just re-installed pip. Get get-pip.py from https://pip.pypa.io/en/stable/installing/ and just run python get-pip.py in your virtualenv. That should overwrite the existing installation and update the SSL certificate.

It seems this issue is generating quite a few questions on Stack Overflow about various packages not getting installed using pip install package-name. So I thought I'll copy over my answer from here for more clarity on the issue:

The solution is to upgrade pip to the latest version.

However, upgrading pip via pip install --upgrade pip may not upgrade it correctly (it will show it's up-to-date even when it's not).

So (for Mac users, for example), we need to upgrade pip as follows:

curl https://bootstrap.pypa.io/get-pip.py | python

What's happening:

Python.org sites are stopping support for TLS versions 1.0 and 1.1. This means that Mac OS X version 10.12 (Sierra) or older will not be able to use pip unless they upgrade pip as above.

This thread explains it (thanks to this Twitter post):

Mac users who use pip and PyPI:

If you are running macOS/OS X version 10.12 or older, then you ought 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

and we recommend you do that by April 8th.

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/

Also, the Python status page:

Completed - The rolling brownouts are finished, and TLSv1.0 and TLSv1.1 have been disabled. Apr 11, 15:37 UTC

Update - The rolling brownouts have been upgraded to a blackout, TLSv1.0 and TLSv1.1 will be rejected with a HTTP 403 at all times. Apr 8, 15:49 UTC

Lastly, to avoid other install errors, make sure you also upgrade setuptools after doing the above:

pip install --upgrade setuptools

Thank you, I've been looking for this solution for hours

A coworker also on macOS v10.12 (Sierra) just solved this by running brew install python@2 and then overwriting the previous version. It seems like the the version off the Python website is not bundling the correct OpenSSL version.

I think someone has also filed a bug for this to Python directly: OS X system OpenSSL deprecated - installer should build local libssl

Your HTTP request to PyPI fails with an HTTP 403 (Forbidden) error:

HTTPError: 403 Client Error: TLSv1.2+ is required for url:

https://pypi.python.org/pypi/pip/json

Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.

On Debian-based systems I'd try:

apt-get update && apt-get upgrade python-pip

On Red Hat Linux-based systems:

yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)

On Mac:

sudo easy_install -U pip

You can also try to update openssl separately.

I successfully upgraded Python 3 on macOS v10.13 (High Sierra) using sudo pip3 install --upgrade pip.

To upgrade the High Sierra version 2.7 I had to use sudo pip2 install --upgrade pip.

I had a similar problem.

The problem was in an old version of OpenSSL linked to the system Python installation.

So I've uninstalled all Python distributions from the system and installed the last Python implementation with brew install python@2.

You can check the OpenSSL version linked to Python like this:

Python 2.7.14 (default, Mar 22 2018, 15:04:47) [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.39.2)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import ssl >>> ssl.OPENSSL_VERSION 'OpenSSL 1.0.2o 27 Mar 2018'

Can you describe how you deleted all versions of Python? This issue is driving me nuts.
@juliushibert I did it in simple stupid way. Just list all python commands in terminal (python, python2, etc) check if it file or link and rm them all.
