In order to build and run Python-LLFUSE you need the following software:

  • Linux, FreeBSD, NetBSD or MacOS X system

  • Python 2.6 or newer (including Python 3.x), installed with development headers

  • The setuptools Python module, version 1.0 or newer.

  • When running under Python 2.x, the contextlib2 Python module from PyPi.

  • the pkg-config tool

  • the attr library

  • A C compiler (only for building)

To run the unit tests, you will need

  • The py.test module, version 3.3.0 or newer

When using Linux, you also need:

  • Kernel 2.6.9 or newer. Starting with kernel 2.6.26 you will get significantly better write performance, so under Linux you should actually use 2.6.26 or newer whenever possible.

  • Version 2.9.0 or newer of the FUSE library, including development headers (typically distributions provide them in a libfuse-devel or libfuse-dev package).

In case of FreeBSD and NetBSD you will need:

For OS-X, you need:

Stable releases

To install a stable Python-LLFUSE release:

  1. Download and unpack the release tarball from

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

  3. Run python -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 python install --user.

Development Version

If you have checked out the unstable development version from the repository, a bit more effort is required. You need to also have Cython (0.29.21 or newer) and Sphinx (1.1 or newer) installed, and the necessary commands are:

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