Migrate from iso639 to iso639-lang

[C0rn3j]

iso639 won't work with Python 3.12, maintainer said this February that they are not actively using or developing the library anymore, and that a future version would still need to support Python back to 2.6.

iso639-lang exist which supports 3.7-3.12, which seems perfect for the project as currently minimum marked version for calibre-web is 3.7.

PR in another project that did the same migration can be found here.

EDIT: This may actually not be strictly needed for 3.12 support, but the project being basically dead is not a good outlook for future versions.

I support this. After upgrading to Ubuntu 24 (Python 3.12.3) calibre fails to start:
*** Cannot import iso-639 module, it is needed to run calibre-web, please install it using "pip install iso-639" ***
I haven't been able (yet) to install iso-639 in any way (pip, pipx, apt...) so migrating to lso639-lang looks like a good plan...

You need python-setuptools as a mandatory dependency on 3.12 which might work around the issue for now, it did for me on Arch Linux.

I already have python3-setuptools installed (68.1.2-2ubuntu1), how do you suggest to install iso639 packages? pipx returns an error:
No apps associated with package iso-639 or its dependencies
(same for iso-639)
pip no longer installs anything:
error: externally-managed-environment
and apt can't find the package:
E: Unable to locate package python3-iso639
Any help would be greatly appreciated...

Set up a python venv for it and install all the deps there I suppose, then make calibre-web use the venv

Thanks for your suggestion. Unfortunately, your original comment about incompatibilty between python 3.12 and iso639 still stands. Even if I could install the package with pipx inside a venv, it wouldn't work...

I'll keep trying, anyway, will let you know if there is any advance in the matter.

Unfortunately, your original comment about incompatibilty between python 3.12 and iso639 still stands.

I did get it working on Arch in the end as per the comments above, which uses 3.12, but it newly requires setuptools to be available.
You should be able to get it working.

The newest nightly version already has a fix for it (hopefully):
You will get a message during startup: "Python 3.12 isn't compatible with iso-639. Please install pycountry" (on console, because logging isn't working at the time iso-639 included during startup).
My plan was to wait until the next release to address this:
Option1: iso639 will have a new version with a fix for it -> everything stays as is
Option2: iso639 will have NOT a new version with a fix for it -> use pycountry

Pycountry is already supported as there had been problems with debian (I guess?) in the past.

For now the workaround is delete the line iso639 in the requeirements.txt file and install pycountry

Yes, that worked :-) Thanks a lot
