The last line says that the error's coming out of dbus. Looks like dbus-python on pypi hasn't uploaded the version that they say is updated for python 3.10 yet as well. Their pypi page does seem to suggest that we should use another python library, so switching to one of those shiny new options could be a thing too, would mean one more dependency on pure pypi too. I've made an issue on dbus-python's issue tracker to prompt them to update pypi, but until they update or we move away from dbus Guake does not yet support python 3.10.

[Davidy22]

Went googling a little and this dbus option seems fun, I'll try swapping this in sometime, see how it runs.

[Davidy22]

Alright, dbus-python updated their pypi version to latest, can you do a pip install --upgrade dbus-python and try again on python 3.10?

[Davidy22]

Oh, did it work?

[thegarlynch]

Yeah. upgrading dbus-python worked

I'm unable to install/upgrade 'dbus-python' n Windows OS.
Error:

error: [WinError 193] %1 is not a valid Win32 application
  ----------------------------------------
  ERROR: Failed building wheel for dbus-python

Does this 'dbus-python' work in Windows OS also?
If not does anyone know the workaround?
Thanks in advance.

[Davidy22]

dbus is a library for connecting to a linux service. I was unaware that Guake worked on windows, have you been able to install it before?

have no idea why this occurs

[aussieklutz]

@dongyangTHU - You have asked about an error in a completely different project. This project has found a solution for it, but you likely need to go and check with the developers of whatever project you are using.

[dsaichand3]

Upgrading to the latest version of the pip worked for me.

[Guan-Smile]

In python3.10
change from collections import Sequence to from collections.abc import Sequence
It works!

I have add the corsheader in setting.py
But I can see like this error.
How can I solve this error?

[GOLD106]

I have sent axios post request from reawct.js frontend to Django Backend.
Because there is cors error, I have add the corsheader in Dhango.
