Could not find a version that satisfies the requirement in python

Question

I am trying to create virtual env with python2 in mac os from here. While running pip install virtualenv command in terminal I am getting following error.

Could not find a version that satisfies the requirement virtualenv (from versions: )
No matching distribution found for virtualenv

Are you able to install other packages with pip or is it only a virtualenv related issue? — Martin Alonso, Apr 10 '18 at 10:33
Could be related to the recent pip TLS deprecation. See [this](https://stackoverflow.com/a/49748494/1526703) answer — Anupam, Apr 10 '18 at 15:59

the above commands for my windows 10 and python 3.6.5 gave error `The target principal name is incorrect.` how did get this one working. – Nitish Kumar Pal Jul 03 '18 at 11:08

I had todo `curl https://bootstrap.pypa.io/get-pip.py | sudo python` for it to work on my machine (note the `sudo` before the `python`) – James111 Aug 02 '18 at 05:05
Thanks. Doing this solves my problem. One thing I noticed before/after was that pip seems to talk to "pypi.python.org" before and "pypi.org" after. Seems like some new packages are maintained in a new repo perhaps ???... In particular, I was trying to install scikit-learn. – tuan.dinh Nov 30 '18 at 05:14

We tried the above but they didn't work in our case because we had two versions of python3 on the systems. One via a normal install a few months back and one via brew (on a Mac). When we discovered that, we downloaded and installed the latest version from python.org and as a result the pip was updated too. Once the pip was installed the sudo pip3 install virturaenv command worked fine.

This is not an answer to the question. It should be a comment on the related answer instead. – walnut Sep 07 '19 at 10:44
