# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

/Users/u/Library/Python/3.8/bin

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

Solution

  • I worked through this by installing a non-system version of python3, then installing poetry.

    1. brew install pyenv
    2. pyenv install 3.8.12
    3. pyenv local 3.8.12
    4. curl -sSL https://install.python-poetry.org | python3 -
