Error in building wheel backports.zoneinfo

Using Django Mystery Errors
1

Hello
I am a real newbie in this… and I get this error after trying many things. Is there anything I could do about this? I am using visual studio code to run the terminal for django project. I am trying to install the requirements for django project. Thank you

Here the error:

  note: This error originates from a subprocess, and is likely not a problem with pip.

Thank you very much if there’s any information or solution for this

Quoting directly from the docs at backports.zoneinfo · PyPI

Support for backports.zoneinfo in Python 3.9+ is currently minimal, since it is expected that you would use the standard library zoneinfo module instead.

also

If you do not support anything earlier than Python 3.9, you do not need this library ;

You probably shouldn’t even be trying to use this with Python 3.12.

Thank you very much… i’d changed it to 3.8 but i faced another problem afterwards so I was getting back to 3.12 and I installed it manually. Luckily it works… and I’ve done it.

Thank you very much for your kind response
