"Wrong version of PyObjC C API" -> updated pyobjc -> AttributeError: CFMachPortCreateRunLoopSource

dbieber opened this issue 4 years ago · 11 comments

I just installed aw-watcher-input with poetry.
When I run aw-watcher-input --help I get RuntimeError: Wrong version of PyObjC C API (got 21, expected 20).

What would be required to update aw-watcher-input to work with version 21?

Here's the full stacktrace:

This issue seems to originate in aw-watcher-afk (which depends on pyobjc). It's been breaking the CI for aw-watcher-afk for some time now, hopefully all that's needed is to update pyobjc.

If this CI run passes, then I've fixed it, and I'll update aw-watcher-input in just a moment :)

Answer 2 · 2020-12-28T18:12:05.000Z

aw-watcher-afk CI run passed! Fixed for aw-watcher-input in a6730e2

Thanks for reporting 🙂

Answer 3 · 2020-12-28T18:12:40.000Z

Thanks for your impressively prompt turn around fixing this! 🙏

Answer 4 · 2020-12-28T18:14:21.000Z

@dbieber You're just lucky, I was just about to stop working for the day 😉

Answer 5 · 2020-12-28T18:29:56.000Z

Hmm, even after updating to a6730e2 I still get the same error.

@dbieber Can you give me pip freeze | grep pyobjc? Did you run poetry install again?

If you have the latest pyobjc, it should work (otherwise I'm clueless).

Installing in a fresh virtualenv resolved the issue,

now it starts but with these errors:

From the "working" virtualenv, here's the output of the requested command:

And yes I did poetry install again.

Answer 8 · 2020-12-30T12:43:31.000Z

Huh, that's new. Might be caused by the v21 API/bumping pyobjc to 7.0. ~~It presumably affects aw-watcher-afk as well.~~

Edit: It does not affect aw-watcher-afk since it's been upgraded to use CGEventSourceSecondsSinceLastEventType: https://github.com/ActivityWatch/aw-watcher-afk/blob/master/aw_watcher_afk/macos.py

Answer 9 · 2020-12-30T12:57:58.000Z

@dbieber I've opened an issue in the PyUserInput repo PyUserInput/PyUserInput#61. It looks like an easy fix, but I might be wrong about that.

If you have the time, feel free to give it a shot. Otherwise, I might look into it myself in a few weeks.

Answer 10 · 2020-12-30T13:42:41.000Z

Thanks for looking into it. I’ll let you know if I get a chance to look into it myself before then.

Answer 11 · 2020-12-30T17:56:03.000Z

I logged my progress in PyUserInput/PyUserInput#61.
Switching to Python 3.9 (not sure if necessary) and rolling jedi back to version 0.17.2 partially resolved the issue; now its successfully logging mouse moves. No changes were needed to aw-watcher-input or PyUserInput for this.

Still gives the CFMachPortCreateRunLoopSource AttributeError.

The logging of mouse data seems intermittent, and isn't showing up again on subsequent runs.
