[EN] Can't install pyside6

[ForeverNoob]

Hello,

How can I install pyside6 system-wide?

TIA

Hi and welcome to siduction.

Pyside6 is not available in Debian Unstable or siduction from the archives. To install it, you need the python-installer pip. First install pip itself with

Code: [Select]

apt update && apt install python3-pip
In the next step, you install pyside6 with:

Code: [Select]

pip3 install pyside6
After that, you can start creating Python GUI applications with PySide6 in siduction. Have fun.

Thanks for answering.

This the response of the pip3 install:

Code: [Select]

error: externally-managed-environment



× This environment is externally managed

╰─> To install Python packages system-wide, try apt install

    python3-xyz, where xyz is the package you are trying to

    install.

     
    If you wish to install a non-Debian-packaged Python package,

    create a virtual environment using python3 -m venv path/to/venv.

    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make

    sure you have python3-full installed.

     
    If you wish to install a non-Debian packaged Python application,

ou can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packag

As suggested I tried this:

Code: [Select]

apt install python3-pyside6
The response was:

Code: [Select]

Unable to locate package python3-pyside6

It may just come down to syntax.

Did I say 

Code: [Select]

apt install python3-pyside6
I don't think so.

That doesn't work too. apt response:

Code: [Select]

Unable to locate package python3-pyside6

You need pip3 first, because pyside6 is not in Debian. If

Code: [Select]

sudo apt install python3-pip
does not work, your sources.list is wrong.

Already had that installed. Running

Code: [Select]

pip3 install pyside6
gives the following response:

Sorry man, I'm out. You have to learn how to read. Look at my initial instructions.

The pip3 install command is correct. There's a file on your system marking it as 'externally managed', just like the message says.
Included in the message is a suggestion to use a venv (virtual environment) or use pipx, alternatively it notes a way to override the restriction, at the risk of breaking your Python installation or OS. Your choice how to proceed.
