• Workaround for when poetry cannot find pyenv managed python

  Sander June 16, 2023 at 11:23 am

  I use pyenv to manage python versions for my projects, and use poetry to manage project dependencies. Poetry was unable to find the latest python version, and insisted on creating virtual envs with system python.

  Setting poetry config virtualenvs.prefer-active-python true did not work for me, and neither did poetry env use whatever-version:

  $ poetry env use 3.11
  Could not find the python executable python3.11

  However pyenv can list the the full path to the currently active python, which can be used as a parameter to poetry, so the following worked:

  $ poetry env use $(pyenv which python)
  $ poetry install; poetry run python --version
  

  Update: double check that pyenv is configuring the shell correctly -- $HOME/.pyenv/shims should be in your PATH variable, and your shell runtime configuration file (such as .bashrc / .zshrc) should contain eval "$(pyenv init -)"

  Hope this helps!

• Using python - best practices

  Sander September 9, 2022 at 11:41 am

  This is how I do it:

  1. Manage python versions with pyenv. Modern python comes with pip already installed.
  2. Don't touch system python if you have it, in terms of installing packages, updating it etc.
  3. For projects, use virtual environments using one of the python version installed with step 1. I prefer poetry at the moment to manage them.
  4. Use pipx if you want to install a global utility, so it's isolated from any projects.

  Feedback welcome.
