pyenv and poetry installation on Debian

Introduction

Setting up a python development environment is annoying. We’d especially like to avoid:

  • Using the system python: it may be way out of date, have special modifications, or be required for the system to function (and therefore we should avoid messing with it).

  • Installing packages globally: different projects may require different versions, and the system may have its own package requirements that conflict with ours.

The solution has two components:

  • install and use whatever version of python you like

  • create isolated environments using your preferred version of python for each project

Retrieving Poetry metadata

# 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:

$HOME/.poetry/bin

This path will then be added to your `PATH` environment variable by
modifying the profile files located at:

$HOME/.profile
$HOME/.zprofile
$HOME/.bash_profile

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

Installing version: 1.0.5
  - Downloading poetry-1.0.5-linux.tar.gz (23.37MB)

Poetry (1.0.5) is installed now. Great!

To get started you need Poetry's bin directory ($HOME/.poetry/bin) in your `PATH`
environment variable. Next time you log in this will be done
automatically.

To configure your current shell run `source $HOME/.poetry/env`

.zshrc 

export PATH=$HOME/.poetry/bin:$PATH

source $HOME/.poetry/env

poetry
