Cannot install under python 3.9 due to datrie

[jameshadfield]

Posting here in case others have solutions.

TL;DR Install works under python 3.8

Details

• MacOS 11.5 (M1 chip)
• Python version 3.9.12 (installed via conda)
• Pip 22.0.4

pip cache purge
python3 -m pip install -e '.[dev]'
...

Failed to build datrie
ERROR: Could not build wheels for datrie, which is required to install pyproject.toml-based projects

Same problem occurs when trying to install datrie itself in a clean python environment:

conda create -y -n test python=3.9
conda activate test
python -m pip install --upgrade pip # pip 22.0.4
pip cache purge
pip install datrie
# same error as above

(Temporary) solution

Use python 3.8, where a datrie wheel exists.

It works fine for me:

mamba create -n test python=3.9
conda activate test
sw_vers  # macOS 11.6.1 20G224
python --version  # Python 3.9.12
pip --version  # pip 22.0.4
pip cache purge
python3 -m pip install -e '.[dev]'

Output:

Seems to be the same as Hekstra-Lab/reciprocalspaceship#36 and https://groups.google.com/g/anvio/c/ayvtZoUWbJI but don't see any clear solutions there.

@jameshadfield downgrading to 2 - Usability w/ workaround since the workaround is to use python=3.8.
