The key detail is this path:

/usr/local/lib/python3.13/dist-packages
Downloading pygit2-1.15.1.tar.gz

There is no compatible prebuilt wheel for that pinned pygit2 on Python 3.13, so pip falls back to compiling it. Fooocus' pinned dependency stack is intended for an older Python (the project's working installs use Python 3.10), and the source build then fails because the required native/libgit2 build environment is not present.

The reliable fix is a clean Python 3.10 environment, not repeatedly upgrading pip in the 3.13 environment:

python3.10 -m venv fooocus_env
source fooocus_env/bin/activate
python -m pip install --upgrade pip
python -m pip install -r requirements_versions.txt
python entry_with_update.py

Run those commands from the Fooocus repository and verify python --version and python -m pip --version both point into fooocus_env before installing.

If this is Windows, using the project's packaged download is simpler because it includes its own Python 3.10 runtime. Avoid merely unpinning pygit2: a newer release may support Python 3.13, but the rest of Fooocus' pinned Torch/extension stack is still not validated there. If it still fails under 3.10, include the lines above “Failed building wheel”, because those contain the actual compiler/libgit2 error.
