pip install pyside fails

[Anonymous_Banned275]

Installing pip install pyside fails with error indicating I am using unsupported python version .

I am hesitant to change my python3.10 version - it could break my current application.

1. Can I have multiple versions of python on my system ?
2. Am I installing current version of pyside?

Constructive replies will be greatly appreciated .

Thanks

@AnneRanch, which system do you use? (is it traditional Intel x86 or something else?)
Which OS do you use? (I suspect it is Linux but which one?)
How you installed python?
Have you checked your access rights to site-packages directory? (as it complains it is not writable)
And if you afraid to break your system - have you tried to use python vitrual environment? what is the result of pip install in this case?
Why you try to use first version of pyside instead of pip install PySide6?
