In my case with
fish I added this line to my
set -gx PIPX_DEFAULT_PYTHON "$HOME/.pyenv/versions/3.8.5/bin/python"
It’s roughly the bash equivalent for
As a Python developer, my workflow often involves running multiple versions of Python on different projects. To help me in this task, I use
pyenv which is a wonderful tool to easily install and manage multiple Python versions on your system.
I also have a Python version installed via Homebrew for some formulae that require it. This version is the default for any script if pyenv doesn’t specify any version.
Finally, I also use
pipx which allows me to install python packages in their own virtual environment without messing with my system installation and still have them ready for use on the command line.
My problem is that
pipx will by default use the Python version provided by Homebrew to install the executables. As I keep my system up to date with Homebrew, the Python version often updates. When that happens, all of my
pipx packages break and I have to reinstall them all. Granted,
pipx provides a command to do that easily but I’d still like to avoid the operation.
Thankfully, as documented1,
pipx supports an environment variable called
PIPX_DEFAULT_PYTHON. You just need to point it to your preferred Python interpreter and be done with it!
