Note: This error originates from the build backend, and is likely not a problem with poetry but with systemd-python (235) not supporting PEP 517 builds. You can verify this by running 'pip wheel --use-pep517 "systemd-python (==235)"'.

The same issue occurs when trying to build a wheel pip wheel "systemd-python (==235)" as the command above describes.

I also can't add this dependency directly via git:

$ poetry add https://github.com/systemd/python-systemd

file could not be opened successfully:
- method gz: ReadError('not a gzip file')
- method bz2: ReadError('not a bzip2 file')
- method xz: ReadError('not an lzma file')
- method tar: ReadError('invalid header')

I'm not familiar with details as to why this is occuring, but all I want to do is add this package as a dependency for my project, preferably with poetry. I am not sure if there are other methods of adding this as a dependency to pyproject.toml that would require its installation.

Can you try this : apt update && apt install pkg-config libsystemd-dev python3-dev

[axoroll7]

This python library, downloaded from pypi, will compile on the fly. To prevent this, install this library with the OS package system (apt, dnf, etc), and allow your virtual environment to interact with the system site-packages directory :

• venv : --system-site-packages
• poetry : poetry config virtualenvs.options.system-site-packages true

Many libraries on Linux work that way.

apt update && apt install pkg-config libsystemd-dev python3-dev

installing the librairies, fixed the issue for me.

Sorry for the late response.

This did indeed fix the issue for me.
