Error during carputils installation when installing Python dependency tables

Question

I ran into an error when installing carputils on macOS Monterey 12.3.1, using Python 3.10.

The error is not directly linked with carputils, but occurs when trying to install the Python package tables.

Collecting tables>=3.6.1

         You may need to explicitly state where your local HDF5 headers and

         library can be found by setting the ``HDF5_DIR`` environment

         variable or by using the ``--hdf5`` command-line option.

  note: This error originates from a subprocess, and is likely not a problem with pip.

The installation of tables fails if HDF5 is not available on the system. See the answer above for a solution that worked for me. 

Answer 1

I am using Homebrew as a package manager and could get HDF5 using:

brew install hdf5

This was yet not sufficient for carputils to find the HDF5 library, so I had to run (to be adapted to the location of your HDF5 directory)

export HDF5_DIR=/opt/homebrew/Cellar/hdf5/1.12.2

From the carputils directory, I was then able to install carputils (and its dependencies) with

python3 -m pip install .
