In order to build and run pyfuse3 you need the following software:

  • Linux kernel 3.9 or newer.

  • Version 3.3.0 or newer of the libfuse library, including development headers (typically distributions provide them in a libfuse3-devel or libfuse3-dev package).

  • Python 3.8 or newer installed with development headers

  • The Trio Python module, version 0.7 or newer.

  • The setuptools Python module, version 1.0 or newer.

  • the pkg-config tool

  • the attr library

  • A C compiler (only for building)

To run the unit tests, you will need

  • The py.test Python module, version 3.3.0 or newer

Stable releases

To install a stable pyfuse3 release:

  1. Download and unpack the release tarball from

  2. Run python3 build_ext --inplace to build the C extension

  3. Run python3 -m pytest test/ to run a self-test. If this fails, ask for help on the FUSE mailing list or report a bug in the issue tracker.

  4. To install system-wide for all users, run sudo python install. To install into ~/.local, run python3 install --user.

Development Version

If you have checked out the unstable development version, a bit more effort is required. You need to also have Cython (0.29 or newer) and Sphinx installed, and the necessary commands are:

python3 build_cython
python3 build_ext --inplace
python3 -m pytest test/
sphinx-build -b html rst doc/html
python3 install
