Note: This error originates from the build backend, and is likely not a problem with poetry but one of the following issues with pygit2 (1.18.2)

• not supporting PEP 517 builds
• not specifying PEP 517 build requirements correctly
• the build requirements are incompatible with your operating system or Python version
• the build requirements are missing system dependencies (eg: compilers, libraries, headers).

You can verify this by running pip wheel --no-cache-dir --use-pep517 "pygit2 (==1.18.2)".

Using python 3.14

A new release with Python 3.14 artifacts would fix this, but I think maybe free-threading support is to be finished first?

Simple RTFM response

You need to set LIBGIT2 env var to the place where you installed libgit2 (via CMAKE_INSTALL_PREFIX option). This project's setup.py takes no responsibility in guaranteeing that libgit2 (and related deps like libssh2, openSSL, crypto) are installed/present when building from source.

This has nothing to do with PEP517 compliance. You simply did not check the docs first.

FWIW, lots of issues are raised here expecting pygit2 to have future-compatible deployments. They all don't acknowledge the complexity of building a python library that's implemented in C.
