Support for python 3.9 is urgently required

Anki Desktop
1

Hello, my distro has upgraded python to 3.9 so I can not use anki anymore.
Please, fix the code.

With best regards,
Dmitry

If the packaged version of Anki doesn’t work on your distro, you’ll need to compile it yourself.

3

My distro is Slackware-current.

And I can not compile it myself. At the moment I have been trying to compile v.2.1.16
And after

pip3 install -r requirements.txt
pip3 install pyqt5
pip3 install PyQtWebEngine
pip3 install PyQtWebEngineWidgets

I get the message

ERROR: Could not find a version that satisfies the requirement PyQtWebEngineWidgets (from versions: none)
ERROR: No matching distribution found for PyQtWebEngineWidgets

At the moment I see

If you're running from git, did you run build_ui.sh?

Traceback (most recent call last):
  File "/home/dima/devel/python/anki/runanki", line 3, in <module>
    import aqt
  File "/home/dima/devel/python/anki/aqt/__init__.py", line 32, in <module>
    import aqt.forms
ModuleNotFoundError: No module named 'aqt.forms'

While there was python 3.7 all worked this way

Today I’ve tried to run anki-2.1.35

$ pip install aqt anki ankirspy pyqt5 pyqtwebengine

The wheels on PyPI require an x86_64 Linux, but you appear to be using something else.

7

Doch, I use Slackware-current64, probably, the detection failed.

$ uname -m
x86_64

Ah, it would be because ankirspy only targets Python 3.8. If you’re on a 64 bit machine it shouldn’t be too hard to compile it yourself - if you have trouble with 2.1.35 you may like to try the latest beta version instead.

9

The topic includes “python 3.9”

10

Yes, you’re right. Did you try the beta wheels on https://betas.ankiweb.net/#/? They theoretically will work on Python 3.9.

11

Will try at the evening… Thanks.

12

Which commit will you recommend?

13

I was suggesting the whl files on the download site: https://apps.ankiweb.net/downloads/beta/. It says cp38, but that should be a minimum rather than a specific requirement.

14

What is “cp38”?

15

I think cp refers to CPython, the standard implementation of Python, which is most likely what you have. 38 is for 3.8 obviously.

I can confirm that Anki compiles successfully with Python 3.9.

Thanks, will try

I have run ./run in stable brunch (84dcaa86 (HEAD -> stable, tag: 2.1.35, origin/stable) backport qt5.9 opacity fix).

It returns

While

$ pip install ankirspy
ERROR: Could not find a version that satisfies the requirement ankirspy (from versions: none)
ERROR: No matching distribution found for ankirspy

Are there any suggestions?

I suggest you try what I suggested above, or show what problems you ran into when trying it.

$ cd anki-2.1.36-linux-amd64/

That’s the packaged version of Anki, not the whl files I was talking about, which are in the wheels subfolder. You won’t be able to use the packaged version because you’re using a distro that doesn’t have systemd.
