Note.
I know that many solutions have been proposed in this very relevant post but they are all very different and assume vastly different problems, and I don't want to blindly try one at random just to see what happens.
The problem.
I was working on a Jupiter notebook when I started getting errors (with the kernel, cannot quite remember exactly what, now). After trying a few things and searching the web, it seems the problem is that pip broke, somehow. Namely, I am getting the
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available..
error message. Some further reading suggests that the problem is with homebrew?
This puzzles me for two reasons:
- I don't see what I did that broke pip;
- pip for all of my virtual environments seem broken.
What is the problem, really, and where does it come from?
Setup.
- macOS Catalina 10.15.3.
- pyenv as Python virtual environment manager
- outputs below for Python and pip versions
Some outputs.
The command pip --version with python3.8.2 is very strange. Going through the site-packages of the python3.8.2 install, it looks like pip version is 19.2.3.
The errors are not the quite the same for the different versions of pip.
