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.

It is sometimes because of connectivity issue. Re-running the same command when connectivity is okay solves it.

pip install virtualenv

One of the important reasons for this problem is the lack of proper connection to the Internet. If you have this error to install other modules, try to make sure of your internet connection.

Note: If you use vpn, try to connect and disconnect it once, the problem may be with vpn.
