I'm working on a Python project that uses Poetry for dependency management. Recently, I found a bug in a third-party package, so I cloned its repository to work on it locally. My goal is to integrate this local version of the package into my project, but I've run into some issues. First, I attempted to manually add the package path to my pyproject.toml like this: [tool.poetry.dependencies] buggy-one = { path = './buggy-one' } This does install the package, but not in editable mode, which is not ideal for development. Next, I tried using pip install -e ./buggy-one to install the package in editable mode. Unfortunately, on newer versions of Ubuntu (like 24.04), this results in the following error: error: externally-managed-environment × This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz... The error message suggests using pipx as an alternative, but this isn't suitable for my needs since pipx installs the package in a separate environment, and I need to work on it within my Poetry-managed project. Given these challenges, what is the correct approach in 2024 to work on a local package within a Poetry-managed project on Ubuntu? Is there a way to properly link the local package so that I can develop and test it simultaneously wi New pip message on Ubuntu 24.04 Here the full new message you get if you try to use pip on Ubuntu 24.04: $ pip install gettext error: externally-managed-environment × This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install. If you wish to install a non-Debian-packaged Python package, create a virtual environment using python3 -m venv path/to/venv. Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make sure you have python3-full installed. If you wish to install a non-Debian packaged Python application, it may be easiest to use pipx install xyz, which will manage a virtual environment for you. Make sure you have pipx installed. See /usr/share/doc/python3.12/README.venv for more information. note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. Continue reading...
