ERROR: Failed to build 'notmuch2' when getting requirements to build wheel

[offbyone]

Not just with homebrew; it also fails with uv tool install lieer with the same message (other than the path details being for uv builds)

[lambdadade]

that should be an error with python3-notmuch2
Had the same error on debian.
Installing python3-notmuch2 via apt and pip install . --break-system-packages --no-deps works for me

[offbyone]

Based on weilbith/notmuch2-python-bindings#5 -- which seems to be this one -- the notmuch2 library isn't maintained any more.

[lambdadade]

Yes. That should be the root cause.

Gmail / lieer only had been a "proof of concept" for me
and I spotted this "bug" by accident.
So I wont follow it further.

But it looks like the requirements shall be fixed or this code shall be refactored somehow for the future.

[laarmen]

I don't know the raw pip equivalent, but using pipx I managed to have it work by pointing it to the notmuch2 package that came with the notmuch package in homebrew:

pipx install --system-site-packages -e .

The code itself is correct, the problem is that notmuch upstream don't distribute their bindings through PyPI.

thanks @laarmen

I was also able to install with:

uv tool install git+https://github.com/gauteh/lieer --with /Users/gcgbarbosa/Library/Caches/pip/wheels/94/b6/7b/2aaa1acee871b6ecf48e1a65c93918c90573881c262b57824b/notmuch2-0.40-cp312-cp312-macosx_11_0_arm64.whl

I got the whl from homebrew
