Build error with python-lzf while updating package with poetry

I am trying to update a package via poetry, but get an error with python-lzf which is one of the dependencies.

$ poetry update package_name

Note: This error originates from the build backend, and is likely not a problem with poetry but with python-lzf (0.2.6) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "python-lzf (==0.2.6)"'

However, this works just fine.

$ pip wheel --no-cache-dir --use-pep517 "python-lzf (==0.2.6)"

Solution

  • The Python development headers are missing. The file Python.h is part of python3-dev. It must be installed, try:

    python --version                 # say python 3.13
sudo apt install python3.13-dev  # install the appropriate dev package
