Pip install fails on macOS 12.5 (Apple silicon M1)

[adno]

I tried to install the current version of CyHunspell (1.3.4). pip install cyhunspell first fails with "package hunspell was not found in the pkg-config search path". When I add it to the path, it fails again because it cannot find 'hunspell/hunspell.hxx' in the include path.

The following command works OK as a workaround:

PKG_CONFIG_PATH=/opt/homebrew/Cellar/hunspell/1.7.0_2/lib/pkgconfig pip install --global-option=build_ext --global-option="-I/opt/homebrew/Cellar/hunspell/1.7.0_2/include" cyhunspell

Details of my configuration and the error messages follow.

My configuration:

• macOS 12.5
• Apple silicon M1
• hunspell installed via homebrew
• python 3.9 or 3.10 (both fail the same way) in a conda environment

First error message (pkg-config):

I had the same problem. I could make it work by first cloning the repository and install from there :

git clone https://github.com/MSeal/cython_hunspell.git
cd cython_hunspell
pip install .

You can test it works properly :

cd ..
python -c "from hunspell import Hunspell; h = Hunspell(); print(h.spell('correct')); print(h.spell('incorect'))"

Update: The problem and the workaround is still the same even for macOS 13.1 and Python 3.11, depending on where and which version of hunspell you have, a command similar to this will work:

PKG_CONFIG_PATH=/opt/homebrew/Cellar/hunspell/1.7.2/lib/pkgconfig pip install --global-option=build_ext --global-option="-I/opt/homebrew/Cellar/hunspell/1.7.2/include" cyhunspell
