Instructions on how to install afew with Python3.12(.3)

[xaltsc]

Hey,

As for my particular setup, I'm running Alpine with Python3.12.3. I couldn't find a way to (re)install afew as an unprivileged user.

I'm looking to install any version post the latest release, but the latest possible one would be ideal.

I essentially followed instructions here https://afew.readthedocs.io/en/latest/installation.html (with commit a3f6f6a as suggested by @GuillaumeSeren on IRC) and variations thereof, i.e.

$ python -m venv --system-site-packages .venv
$ source .venv/bin/activate
$ python setup.py install --prefix=~/.local

for which $ afew gives the following error

Traceback (most recent call last):
  File "/srv/user/.local/bin/afew", line 33, in <module>
    sys.exit(load_entry_point('afew==3.0.2.dev61+ga3f6f6a', 'console_scripts', 'afew')())

$ python -m venv  .venv
$ source .venv/bin/activate
$ pip install setuptools
$ pip install notmuch
$ python setup.py install --prefix=~/.local

for which $ afew gives the following error

During handling of the above exception, another exception occurred:

I also tried to just pipx install afew with which running $ afew gives the following error:

ImportError: cannot import name 'SafeConfigParser' from 'configparser' (/usr/lib/python3.12/configparser.py). Did you mean: 'RawConfigParser'?

pipx install --python 3.11 --fetch-missing-python afew also fails because musl.

Hey @xaltsc ,
Can you try with a newer release like 3.0.1 + python3.12 ?

I think at least some of those issue where fixed already,
also try a isolated venv without using system libs

[xaltsc]

The first two with 3.0.1 give the exact same errors.

What do you exactly mean by "an isolated venv without using system libs" ?

[hendursaga]

This looks like a duplicate of #341. See https://docs.python.org/3/whatsnew/3.12.html#configparser for why the error is shown.

The way I managed to make it work was to:

a) Amend the readfp method call to read_file, as suggested by @hendursaga (refer to the pull request mentioned above).
b) Also amend the notmuch-python-bindings to accommodate the changes in configparser.

EDIT: If you have a recent version of notmuch installed on your system, this issue has already been addressed on the notmuch side. You're likely already aware that the PyPI version is an outdated mirror of the source without the past few years of development—I wasn't aware of this, so my apologies.

Then you can use pipx to install:

pipx install --system-site-packages /path/to/afew

This should now work correctly.
